Huh, Ive never had this problem. Alot of people take out the water bowls when introducing pairs together. I would start by taking out the water bowl and removing as much of the wet paper as you can and get a towel and dry and soak up some water if there is alot without disturbing them too much (dont worry about putting new paper down untill they unlock and you separate). Some dont mind if you intrude on them while in the act and some other do, so your just gonna have to find out. If they do separate which I doubt, they will lock again so dont worry about it. But its not good to let any snake sit in a wet tub for an extended period of time. Or if its not that much water and its not cooling down the tub or tank you can just wait till they unlock which can be anywhere from a couple hours to a couple of days. Def dont try to separate or move them Just work around them and they may just ignore you.
