Yeah, I figured as much - I have done 2 AK runs subsequently and didn't lose enmity once as far as I saw. Had a Reliced MNK in the group once, was no problem. I am coming to the conclusion that the BLM was intentionally messing with me because he was offended.

Now if I could only get enough gil to buy my Battledance III materias so I could move on with my Relic quest!!
