Help Question Regarding Watch and Learn Sudowoodo

[SuperTrainerSamYT]

I have a question regarding the attack "Watch and Learn" on the Sudowoodo printed in BREAKpoint. For those unfamiliar with the attack, here is the exact text:

(F)(C) Watch and Learn
If your opponent's Pokemon used an attack during his or her last turn, use it as this attack

My question is if I use a GX attack, and next turn my opponent uses Sudowoodo's Watch and Learn attack, but have already used their GX attack for the game, are they still able to copy the GX attack I just used? Also, if my opponent has not used a GX attack, and copies a GX attack, would they have to flip their GX marker over?

Thanks.

this ruling from the compendium applies

Q. Can I have Clefairy's "Metronome" copy a GX attack, and if so does it use up my "one GX attack per game"?
A. Yes you can, and yes it does. Also if you’ve already used your GX attack for the game, then you cannot choose a GX attack with Metronome. (Jan 5, 2017 TPCi Rules Team; Sun & Moon FAQ)
