moving CCSprit to the left causing strange movement all other direction are working

try to move simple CCNode with CCSprit as member to the left side and it give me strange result , all the other dirctions working fine that is right , up , down only left give me problem the sprit is moving way out of the screen . here are the functions i have
they are called on ccTouchMoved
the job is to take the near sprite (Gem* other ) and replace with the current

//THIS IS THE PROBLEMATIC FUNCTION 
void Gem::setGemPositionAnimationLeft(Gem* other,bool bMatch)
{
    CCLOG("setGemPositionAnimationLeft");
    CCPoint OrigGemPoint  = getGemPos();
    CCPoint otherOrigGemPoint =  other->getGemPos();



    CCMoveTo *otherMoveRight = CCMoveTo::create(0.3f,OrigGemPoint);
    CCMoveTo *otherMoveLeft = CCMoveTo::create(0.3f,otherOrigGemPoint);
    CCMoveTo *origMoveRight = CCMoveTo::create(0.3f,OrigGemPoint);
    CCMoveTo *origMoveLeft = CCMoveTo::create(0.3f,otherOrigGemPoint);

    CCSequence*  otherSequenceActionRightAndLeft = CCSequence::create(otherMoveRight,otherMoveLeft, NULL);
    other->mySprite->runAction(otherSequenceActionRightAndLeft);


    CCSequence*  origSequenceActionLeftAndRight = CCSequence::create(origMoveLeft,origMoveRight,NULL);
    mySprite->runAction(origSequenceActionLeftAndRight);
}

void Gem::setGemPositionAnimationRight(Gem* other,bool bMatch)
{
    CCLOG("setGemPositionAnimationRight");
    CCPoint OrigGemPoint  = getGemPos();
    CCPoint otherOrigGemPoint =  other->getGemPos();



    CCMoveTo *otherMoveLeft = CCMoveTo::create(0.3f,OrigGemPoint);
    CCMoveTo *otherMoveRight = CCMoveTo::create(0.3f,otherOrigGemPoint);
    CCMoveTo *origMoveRight = CCMoveTo::create(0.3f,otherOrigGemPoint);
    CCMoveTo *origMoveLeft = CCMoveTo::create(0.3f,OrigGemPoint);

    CCSequence*  otherSequenceActionLeftAndRight = CCSequence::create(otherMoveLeft,otherMoveRight, NULL);
    other->mySprite->runAction(otherSequenceActionLeftAndRight);


    CCSequence*  origSequenceActionRightAndLeft = CCSequence::create(origMoveRight,origMoveLeft,NULL);
    mySprite->runAction(origSequenceActionRightAndLeft);
}

void Gem::setGemPositionAnimationUp(Gem* other,bool bMatch)
{

    CCLOG("setGemPositionAnimationUp");
    CCPoint upperOrigGemPoint  = getGemPos();
    CCPoint otherOrigGemPoint =  other->getGemPos();



    CCMoveTo *otherMoveDown = CCMoveTo::create(0.3f,upperOrigGemPoint);
    CCMoveTo *moveDown = CCMoveTo::create(0.3f,upperOrigGemPoint);
    CCMoveTo *moveUp = CCMoveTo::create(0.3f,otherOrigGemPoint);
    CCMoveTo *otherMoveUp = CCMoveTo::create(0.3f,otherOrigGemPoint);

    CCSequence*  SequenceActionUpAndDown = CCSequence::create(moveDown,moveUp, NULL);
    other->mySprite->runAction(SequenceActionUpAndDown);
    // upper gem move down action
    CCSequence*  SequenceActionDownAndUp = CCSequence::create( otherMoveUp,otherMoveDown,NULL);
    mySprite->runAction(SequenceActionDownAndUp);

}

void Gem::setGemPositionAnimationDown(Gem* other,bool bMatch)
{
      CCLOG("setGemPositionAnimationDown");

      CCPoint upperOrigGemPoint  = getGemPos();
      //CCLOG("Gem %s %s upperOrigGemPoint! x:%f ,y:%f",getImageName().c_str(),getGemId().c_str(),upperOrigGemPoint.x,upperOrigGemPoint.y);
      //the down gem pos , that the upper gem suppose to go when dragged down
      CCPoint otherOrigGemPoint =  other->getGemPos();
      //CCLOG("Gem %s %s moveToPoint! x:%f ,y:%f",other->getImageName().c_str(),other->getGemId().c_str(),moveToPoint.x,moveToPoint.y);


      //down gem move up action    
      CCMoveTo *otherMoveUp = CCMoveTo::create(0.3f,upperOrigGemPoint);
      CCMoveTo *moveUp = CCMoveTo::create(0.3f,upperOrigGemPoint);
      CCMoveTo *moveDown = CCMoveTo::create(0.3f,otherOrigGemPoint);
      CCMoveTo *otherMoveDown = CCMoveTo::create(0.3f,otherOrigGemPoint);


      CCSequence*  SequenceActionUpAndDown = CCSequence::create(otherMoveUp,otherMoveDown, NULL);
      other->mySprite->runAction(SequenceActionUpAndDown);

      // upper gem move down action    
      CCSequence*  SequenceActionDownAndUp = CCSequence::create( moveDown,moveUp, NULL);
      mySprite->runAction(SequenceActionDownAndUp);

}

the answer is :
is to stop actions before doing any action on the node .
not sure why? can someone explain the logic behind ?
