If one mate is Scripturally Free To Remarry™, so is the other one - however they Committed Adultery™ as far as the legalistas at Bethel™ are concerned, despite the fact that they are, in the eyes of the law of the land, divorced and both free to remarry.
If you want to get sticky about it, the bible actually says that if one mate does not Render The Marital Due™ (in this case by rejecting the wife and divorcing her without Scriptural™ grounds) they are considered bloodguilty because they have set up the rejected mate to commit adultery. The WTS usually applies this to a wife who refuses to have sex with her husband, you know, because a JW male just can't keep it in his pants unless wifey is servicing him whenever he gets an itch down there.
I really wonder why that angle has not been applied to this jerk.

That only applies if they wish to remain JW. If they are DFd and don't give a crap about WTS rules, they can do whatever they like. Actually, if they are DFd and remarry, they can petition for Reinstatement™, but that may not be considered until the Innocent Mate™ either remarries or dies. It all depends on the Elders™ involved on the Judicial Committee™ and who you are/were within the Congregation™ at the time.
You can bet that if the Innocent Mate™ was an Elder™ or Ministerial Servant™ who beat up his wife and she fled for her own safety, and she was seen with some gay male friends she worked with, she would be DFd for Adultery™ in a heartbeat, and the Innocent Mate™/Elder™ could remarry within a month so he could start smacking around his next victim. [I know of an incident like this!]
