Not a bug. Its a feature to give the enemy one last chance of finishing someone before they go into invincibility. Its to help prevent revivetrains.

so you must wait a minute instead of getting finished right before it triggers

Yes, and its consistent with all medic/help ups. The moment you are revived/begin the getup animation you count as alive again, and selfrevive did its job and starts the cooldown.
Example: 1 second before you can respawn you see a medic approaching. You hold out so he can revive you, but you get killed while getting up. High chance that you catch a 25 second respawn because it puts you in the new respawn wave.
My advise if, someone is already trying to finish you stop the revive and save it for another time.
