Further google search indicates that substantial RAT deployment takes 2 seconds. If they destroyed the AC bus 1 & 2 sources on the engine scrapes, there might be a chance that the RAT was also destroyed before becoming airborne again. If the crew were stressed enough to land gear up (rated as impossible by some), imagine the additional stress if this was immediately followed by battery backup and two failing engines!
Morales of this story might be remain alert following a good night's sleep, be well hydrated, be really sure to lower the gear for landing or start the APU if you think you might do a gear up touch and go.
