If a guide wants to share some of his gas with you to extend your dive, and you're okay with it, fine.
As for calling the dive a bit early, if you are basically back at the boat (e.g.: milling around under it, can see the ladder) and want to head back up alone, if conditions are benign, I'm fine with the diver going alone. His buddy can either head up and exit at the same time, or mill around under the boat and head in when he's ready. Assuming all involved are adults responsible for themselves (not in a student role), viz. is fine, etc...
