The log was confusing to me as well, because I read it to mean a single-length AB exposure pair. It wasn't until I realized that the exposures were piggy-backing on MaNGA that I understood. Kaike and Steve - would it be worth adopting a standard format for the observers to report the summary of the nightlog?
