Totally agree with Rich but this guy must have already been in panic mode before he hit the surface and lost all sense of procedures. I saved a lady on a dive that was under extreme panic and she never knew who helped her until 1/2 hour later when she became coherent enough to ask. In that situation I didn’t release her weight belt as we were moored on a buoy above a wreck with 15 other divers on the bottom. I think every situation is different but I wonder who was budded up with him and what they saw or experienced.
