Having served myself, and knowing others who have joined, I know for a fact that joining the military is not a temporary absence. I also know there's no way he's enrolled in even one college course, because for no less than the first year of military service, there is flat out no time for college. With no exceptions I'm aware of, the first termer military member isn't even allowed to enroll in any college courses until they have completed basic, completed their tech training, and certified at what non-military would call "the journeyman" level in whatever job they have been trained for. If he joined in June, there's no way all that was done before the end of the tax year.
So the enrollment requirement can't possibly be met, since he was not enrolled in any course of study in high school that would qualify as an undergraduate program.
