Position keyframe equality

How do i check if 2 keyframes have the same value?

I have 1 layer in composition with 2 identical keyframes. But when I try to compare their values, the result is "false". Why? What am I missing?

Here is the code:

$.writeln(app.project.activeItem.layer(1).position.numKeys);

$.writeln(app.project.activeItem.layer(1).position.keyValue(1));

$.writeln(app.project.activeItem.layer(1).position.keyValue(2));

$.writeln(app.project.activeItem.layer(1).position.keyValue(1) == app.project.activeItem.layer(1).position.keyValue(2));

Here is the result from console:

2

960,540,0

960,540,0

false

Thanks,
