I believe such scenario would have triggered some kind of load report for G exceedance somewhere in the ACARS messages.

I don't think it was necessary to select one or both Flight Path Directors ON to get the FPV red flags. An issue with one FPD would trigger a separate FD red flag and probably a different fault msg.
