Essential follower health after getting up

Now I'm tired right now, so I might be a little crazy also on mobile, bear with me. I could've sworn than when an essential follower goes down in combat (one knee) they heal back to FULL hp before riding again, however, while using EFF and messing around, I found that they get back up quicker with a teeny bit of health, instead of waiting and getting full. I disabled the mod and it still did the same thing, so am I just crazy, or is this something that the mod does (and if so can I change that)? I'm using beta 13 as well in case it matters (need compatibility with interesting NPCs). I also had UFO previously installed before finding out that it was crap, but I did clean my savefile of the leftover scrips.
