Was it merely understandable confusion under such a tremendous amount of pressure that a relight attempt was performed on both engines
The relight checklist on Airbusses is somewhat confusing, it says in the first part that you should try to relight one by one, then both together. The only difference in the checklist is one letter: first they talk about "Engine Master" then "Engine Masters". I had trouble to find the difference myself several times in a simulator.
I guess considering the time available Jeff Skiles had no choice than to try everything he could. I would have done the same.
There wasn't much thrust there anyway. The only thing the engine delivered was electricity and hydraulic pressure.
