I have been going over this sweep in class recently, and we use that exact grip! Possibly because that is my coach.
As best as I can recall (and has been suggested), the purpose of that grip is to make slack to be gripped further up the sleeve. You are supposed to grab, sit up, and use the slack created by the initial grip to make a tight grip further up the arm with your other hand.
I can't explain it in reference to other grips, but Jon can. I've invited him to the thread, so hopefully he should be able to explain fully.
I've seen the grip before, but it always been turned vertical after gripping to cut the slack. I used to swear by monkey myself, but I've learned to use pistol for when I'm injured.
I, like most of you, prefer the 'four finger roll' grip, and especially when using it to take away the other person's posts, as seen in that video.
Also, that seam that runs along the undersleeve on most BJJ gis helps to curl the fingers (obviously not to the extent of the 'four finger roll' grip, but still better than nothing).

Sadly, it's blocked here in the office however it might help if mention that a Trad JJ 5th Dan/Judo 3rd Dan - that's the important qualification, has previously instructed myself and others on the use of a grip on the inside of the sleeve (towards the elbow). Crikey! It worked. It gave him Control and fixed my Arm also allowing him to fold it.

For this particular technique that grip will work. I myself prefer the four finger curl grip over any other grip. The four finger curl grip is the hardest grips to break once your opponent has it.
