I do to.
On a high foul ball, at the backstop I'm mostly ahead on PU.
This gives PU the time to avoid being hit by the down coming ball and PU doesn't have to turn around watching the foul ball at the backstop (he can see me by looking straight foreward).
I've started this at the moment I was working with a (almost) deaf PU. He asked me to give him as much help (in signals) as I could give. Now my partners like it all!!! And are starting to do it also...
