Moving around normally despite being downed

[Lochesh]

At the last possible moment, since my Nekros was about to get downed, I switched to my Focus mode (Vazarin) to heal myself up. However, my frame got still downed for whatever reasons while I was still in Focus mode (might have been perfect/unfortunate timing on an attack from enemies in the Amarna Survival on Sedna, ~ 20 minutes in), popped back into my warframe despite the warning signs screaming I was downed. For whatever reasons, I managed to still run around as if nothing had happened, jumped, skipped, shot things, meleed, and did anything else considered normal when not being downed. My friend did revive me while the timer had about ten seconds left, but overall, it was as if nothing had happened in the first place.
