As I understand the rule in question, the idea isn't that the specs between an on or off-board compressor are the same, but that the off-board compressor is governed by the control system. Pressurizing via the control system gives the cRio the ability to shut off the compressor once the electronic pressure switch indicates appropriate pressure has been reached.
Pressurizing manually with a non-controlled compressor opens the possibility of exceeding the legal storage pressure (even if only by a slight amount before the emergency relief valve pops).
