This seems like a good way to get a double engine failure on takeoff - that's when one retracts the gear.
It's also a good way to get a single engine failure on takeoff - in a marginal power drop situation, one ECU might reset but not the other one.
I am an electronics hardware/software designer and reckon this is very poor design. Handling power transients isn't rocket science. But you should see some of the design defects in Honeywell autopilots. No hardware watchdog at all. For some reason, the people that design electronics in aviation do the most stupid things.
