Crossing the weak hand thumb behind the grip is sometimes used on revolvers. This shooter was mostly a revolver shooter before his mishap. He may have learned to put his thumb back there specifically to keep it away from the weak hand side of the revolver. People with long thumbs can get their thumb up near the front of the cylinder on a revolver where it can get burnt!
But if he uses that same grip with the semi-auto, slide bite is almost inevitable.
Some people call it a "flying thumbs" grip. Both thumbs are on the weak hand side of the pistol. Ends of thumbs are pointed almost upwards. They can be touching the slide itself. In fact, this can be safer than the thumbs forward grip in some cases. If the shooters thumbnails are right at the edge of the slide (as may occur with thumbs forward grip), it is possible to catch the edge of the fingernail in the slide lock notch. That is likely to peel a piece of the nail back as far as the cuticle. A painful end to a shooting session. However, most trainers teach thumbs forward and below the edge of the slide.
Regardless of which method you choose, work to be consistent with it.
