Button Layout Question

So I’m playing horde the other night and while the leaderboard was up between waves this guy was able to vault cover and grab the taps. Is this because he had a different button layout?

I use the default layout so if I don’t start collecting a tap before the leaderboard pops up I can’t until it goes away.

So 3 things

1 if you have your gamer tag highlighted you can run

2 if theres an AI in the lobby and you have them highlighted you can still run and vault and pick up ammo

3 if you pull the map up you can do all the above. The only thing is if you do this and you keep the map up you will get the waiting for players thing

For the power tap, hold X before the board shows up and as long as you keep it pressed it will keep working. Same goes for running or grabbing ammo.
