Yea. I don't know that I like it myself. It is fiddley, which I don't like. By making it less fiddley, I will make it too complex. I'll probably toss it without even giving it a try at the table, to be honest. That being said, however, you are wrong that surrounding an enemy should not make it harder to hit. Too many people attacking a single target get in each other's way. They make it harder, not easier, to fight effectivly. It is a real world concept. I'm not particularly adept at combat myself, but some friends of mine who have practiced various martial arts have said that 4 or more people attacking the same target tend to become a liability rather than a boon. That's where I got the concept from. I also like the fact that position can both be used to gain advantage or to stop other people from gaining advantage (by having two allies fight back to back). It's cinematic in a way I like. Unfortunatly, the fiddley quality I detest, and I have not thought of an elegent way to get rid of that quality.
I know it wasn't a point you raised, but as to whether this is a thing in "real life" or not, I would say it's largely irrelevant. The more important questions in my view are (1) Does this achieve the goal of adding interesting tactical choices? and (2) Will this make the play experience better? If the answer to either of those questions are "No," then I say toss it. An in-world justification can always be added later if it's even needed.
