It even sets the never-used-again validInput to false and it has a comment next to the superfluous, unused repeat-loop condition, causing even more confusion about how the loop is exited. That confusion is what led to the OP starting this thread, because it makes the code confusing and mysterious.

This code is better written with an unadorned “repeat” to make it clearer that it repeats until some test within the body of the loop returns from the surrounding handler.
