He's delaying the inevitable. The only viable reason as to why he'd extend it this shame ruling, or even make it in the first place, is to allow his aides to search the legal code for some sort of precedent that would allow him to make the ruling. This is the basis of lawfare. Make a ruling first, whether or not it's legally justified thru already established law or legal precedent, and then go back and search for that justification, and, if you have to, extend the original ruling ad nauseum until you find that justifying law or precedent. Lawfare isn't just about using a person or entity enough times, attempting to bankrupt them or wear them down to a point where the defendent gives up.

Boasberg regularly used lawfare as a bludgeon to allow his staff the time they need to find the legal justification for his whacked out rulings. Sometimes he's successful, but most of the time he's not.
