I'll just jump straight into it.
You RPS another RED teammate before the next round where you become BLU (Death), you win. Next round, you control (but not really -- you are pretty much stuck to the RED player moving freely until the timer for "controlling" the player stops). As always, if that player survives, you'll teleport to him. Except ofcourse you'll teleport as BLU and, well you're probably dead before you realise.
