I understand why it is viewed as 4 across. Ian from HKG has made an excellent post on this in another thread.
Just from looking at your first link, I can see clearly that the seat in the bed position has direct aisle access, but is not actually on the aisle. Instead you have a tiny gap between 2 other seats, which from the seat plan are ‘G’ seats, in which to pass.
The ‘G’ seats are on the aisle and the 2 seats in the middle are not on the aisle, but have direct access to it. This is as clear as day, so surely you can understand my view on this now?
