Confused about windshield wiper motion

[tdnxxx444]

I have read and search the threads on here but am still confused as to what the windshield wiper motion forehand looks like. Here is a video of the closest thing I can find. http://www.ee.surrey.ac.uk/Personal/Q.Luo/tennis/sampras04.swf

Is that correct? If so, is this motion ideally meant for semi-western or western grips? Also, are eastern grips meant for this motion?

not really, Sampras wasn't using windshield wiping.
it's mostly for guys with Western grip.
avoid it.

what Sampras is doing there it's the "reverse FH"

not a perfect pic, but what you see in Figs 1 & 2 here are closer to windshield wiping:
