If you forget to disengage the altitude hold whilst the fuel flow re-establishes itself, you can very quickly find yourself going very slowly indeed, as the autopilot struggles to hold altitude at the expense of your airspeed.
I can't say that i've ever lost very much (if any) height during this process, but it is critically important for the pilot to be in control, rather than the 'idiot savant'...
