the reason i commented that was cuz it didn't make sense to me. In my opinion, it seems like it'd be the same effect as to him taking it himself, cuz he still has to swallow the water right? And from the scene right before he seemed to be unable to swallow anything, not even water.
And it genuinely was in a light hearted manner not in a malicious way but if you guys wanna take it that way then be my guest.

ah yes kissing while the other person isn't exactly conscious.
