hitTestPoint Trouble

programming flash

Can’t understand why the first hitTestPoint works only at the intersection of figures.
Please help.

import flash.geom.ColorTransform;
var color:ColorTransform = new ColorTransform();;
 
//Align with ss1
     higlight.x = ss1.x;
     higlight.y = ss1.y;
//Check mouse hit and highlight figure
    if (higlight.hitTestPoint(mouseX,mouseY,true)) {
        color.redOffset   = 50;
        ss1.transform.colorTransform = color;
    } else {
        color.redOffset   = 0;
        ss1.transform.colorTransform = color;
    }
 
//Align with ss2
     higlight.x = ss2.x;
     higlight.y = ss2.y;
//Check mouse hit and highlight figure
    if (higlight.hitTestPoint(mouseX,mouseY,true)) {
        color.redOffset   = 50;
        ss2.transform.colorTransform = color;
    } else {
        color.redOffset   = 0;
        ss2.transform.colorTransform = color;
    }
