Bug - Able to revive teammates as an Assault?

So, ran into a n interesting bug today.
I was able to revive any of my teammates -- yes, those not in my squad -- while as an Assault. I double and triple checked. I was able to put down a spawn beacon, but I was able to revive a non-squad mate.
So this is how I think it happened:
- Previous round, I was a Support. (Tsuru Reef. Different mode)
- New round starts (countdown almost complete when I join).
- I switch to Assault using the Y button (change class after game starts button?)
- Then carry on as usual.
As teammates start falling over, I see the blue icon to revive. I try it. It works.
