Bug: Switching Moves during Double Battles

Upon using a switching move such as U-Turn or Volt Switch, a bug presents itself wherein if the faster pokemon uses a switching move, the slower pokemon is able to reselect a move mid-battle. This is particularly troublesome for players who are then able to redirect moves to knockout an already weakened pokemon. 

Initially, it was thought that it only affected pokemon that held choice items. This was later disproved when testing pokemon without the choice band/scarf also yielded the bug.

This is a detailed example of the battle that took place:


Greninja max speed EV and IV uses U-Turn on a Skarmory, player also selects Knock Off from a Azumarill holding a choice band. After the u-turn successfully hits, the player is then able to select a pokemon to switch out to (was galvantula in this case). The player is then able to reselect a move on their pokemon (Azumarill uses Waterfall against Skarmory) to knock it out. 

This was also tested with a Sandslash holding no choice item and suffered the same effects.

So in a double battle, Volt-Switch and U-Turn if used by the faster one of your two pokemons let you pick MID BATTLE again the move of the slower pokemon.

I'm hoping the description is fine.
I can try and provide more infos if needed.
