Other than the last two minutes in each half, I don't think there are any rules that require the offense to let the defense substitute players in the hurry up unless the offense substitutes or the clock is stopped on a penalty.
As far as I know, the only rule is if the Pats substitute, they must allow the defense to substitute too. Also, in the final two minutes there are additional rules that disallow fake substitutions.
I could be wrong, but I think the Pats do run the hurry up on downs with incompletions.
