I don't understand the explanation

Expected Behavior

AFter the third meow, the cat should stay facing leftwards as it moves up.

Program is where cat moves in square from top left to top right, bottom right to bottom left and back to top left so at bottom left.

I ask the owl and don't get an explanation that is sufficient.
I'm wondering if this is a problem with Scratch or how I can change my program so the cat stays facing left as it move back up to top left.
