as the course fee is for training.
I see no problem with a buddy assisting with surface buoyancy following an alternate air source ascent. I teach the person donating air that it is their responsibility too to be certain that their buddy achieves positive buoyancy on the surface. And just in case, I assign the buddy two jobs on the surface - 1)maintain buddy contact, and 2)keep the octo in front of their buddy's face so that if he/she slips below the surface, they can resume breathing from the reg.
But in a Controlled Emergency Swimming Ascent, the student must demonstrate that he/she can achieve positive buoyancy at the surface without any outside assistance. Presumably, if they needed to do this in a real OOA situation, it's because their buddy is not around to help out. Don't overlook dropping (or handing off) of the weight belt as a great way to achieve positive buoyancy quickly. Then orally inflating the BCD should be much easier.
