Not sure if linking to this is useful or not, but in this [Random Doubles] battle, my Heliolisk, from the start, had the movie "Thunder" twice. I used one on one turn and one on the other, and it showed the PP correctly on my end but when I hovered over it to see what opponent sees, it said "Thunder (14/16)". (I used the moves in the last 2 turns, if that's useful.)
