You're looking at this problem with FT knowledge, and assuming the other PAX had similar knowledge.

It is far more likely that the guy the row behind you was a clueless tourist PAX who heard his name and just followed the instructions, assuming he was just the luckiest ....... ever, and the GA/FA was simply off a row.

Unfortunate, but I have to say, kinda funny at the same time.

On the flip side, you were asleep, so not like you missed anything.

(I like F because it's much easier to get to sleep in the first place.)
