In my companies operation we have a similar SOP. With us, the Captain will start the "Flow" by selecting the APU bleed “Off”. Look closely at your companies SOP to see exactly what the trigger is to start the “After Start” flow (Normal Procedures checklist in QRH 3.03).

To prevent such an occurrence, I simply wait until I have the “All Clear, ready to disconnect call” from my ground crew, then select the APU bleed off. This eliminates the chance of such a problem.

Again, most importantly, since everyone should be singing from the same page of music, use what's in your SOP. That’s what EVERYONE involved will expect.
