My question is how is the APU BLEED connection with ENGINE BLEED related to safety before engine shutdown?
FCOM / SOPs / Parking ->
APU Bleed.....ON, just before engine shutdown, to minimise odours of engine exhaust fumes air conditioning.
Your company procedures may vary but I doubt it's after ENG Shut down.
Hope this helps.
