The transfer switch is rated to function with heavy loads (such as air conditioner) being active when engaged if you have auto temp start for the generator. Many of us have animals and keep the temp start active when there's a chance of hot weather driving up inside temps.
i disagree with the way you 'think' it functions
the stat clicks on calling for power
the ems auto starts the genset
after the warmup delay the transfer switch closes
then the ems allows power to the A/C
the power surge goes thru 'closed contacts' of the transfer switch
IF the A/C was pre-engaged and the contacts closed, there would be a tremendous arc from the compressor 'star up spike load' up to 10x what the run current is, that could be 120amps or more arc on the contacts
