I have put some more thought into it, here is how it would work:
A period is defined as lasting from ovulation to ovulation. You can reassign it at any point in that cycle, but only ever the specific period you are currently experiencing.
A man only experiences multiple periods at once if he's assigned them by people who are ovulating on the same day. Since human menstruation is asynchronous, even if he's assigned multiple periods, it's much more likely he'll experience them successively.
He will have all the symptoms that come with that specific period.
Menstruation won't kill him. It's perfectly natural. Bodies are built to withstand it. He won't lose that much blood. Most people experience only mild symptoms anyway. Even a couple simultaneous periods won't kill anyone.
If he's assigned a lot of periods, hundreds to thousands, then yes, that could kill him. But lbh if he pissed off that many women, he probably deserved it.
Boys will become eligible for periods at age 14 and age out of it at 65. To keep it fair, anyone 55 or older at the time of implementation will remain eligible for the rest of their life.
It will not be possible to trace a period back to the original owner.
Once a period is reassigned, there's no way to stop it or take it back. He'll just have to deal with it.
