Cured poison without antidote (co-op game)

[QueenPixxa]

A few days ago I was poisoned during one of our co-op adventures, and chose not to take the antidote until we killed all the snakes on that particular island.
After a couple of (in-game) days I was down to less than 1 heart, and very shortly after I died.

I don't know how many of you have played co-op, so I briefly explain: if you run into trouble (ie. drown), your mate can come to your rescue and administer a bandage; after that, you are revived. I haven't yet found myself in a situation where I couldn't be resuscitated.

Because my health bar was so low, and I was also poisoned, I thought I couldn't be revived; instead, with my great surprise, I found out that not only I was revived: I was also cured from poison, without taking any antidote!
I still had the poison signs on my arms for a couple of days, but my watch stated clearly that there was no poisoning, and eventually my arm turned back to its normal clear state.

Has this happened to everyone who plays co-op and ran into the same predicament, or my game is bugged?
It is nice to get cured of everything in this simple way, but this bandage-cures-all is too big of an advantage, in my opinion, especially when compared to solo playing.

Tonight I recreated a similar situation; the poison state was not so progressed (4 hearts); I drowned myself, and after having the bandage applied, I was again cured of the poison as well. That first time was not a fluke: it is the way the game works in these circumstances.
Or it only happens to us? Please, co-op players, let me know.
