Why isn't last teammate's assist mapped to both buttons on trio?

[Nuuance]

I remember @Mike_Z saying a while back being confused why last assist was only mapped to one button on death or something...same here. I have left bumper and left trigger...why isn't the assist on both after only left with 2 players?

I keep pressing the wrong button and am like "there's no one else left to tag...who else would i be wanting" right?

Eh?
I'm pretty sure what you remember was me mentioning that in MvC3 when you lose a character you can't call assists/tag with that assist button anymore. (It's why things like the Kubota Escape work.)

In SG, once a character on a trio is dead, all assist and tag combinations work for the remaining character.
You sure it wasn't that they were locked out and you just didn't notice? :^)

tl;dr to answer the title question, it is mapped to both buttons.

Oh really?? Wow perhaps it's a bug or maybe something funny was happening. Thanks for the patience man. I'll try it again & see what's happening
