Asiana Club - Seat pitch 50" or 60" in business 747s

I was browsing seatguru and noticed that the site lists seat pitch at 50" for the 74E (Combi) and no power outlets, while the normal 747s are 60" with power. Since the 74E only has C seats in the upper deck (AFAIK), does this mean that the seat pitch is only 50" on all upper decks (no power) for both planes, while 60" is only found on lower decks (with power)? Or is seatguru all messed up?

Or is seatguru all messed up?

That's the correct answer. The lone Combi with 50" C seats was converted into a freighter last year.

Thanks!
