I'm finding the seat map on the BA app very confusing. I'm really looking forward to our first trip on the UD of the Queen of the Skies soon and actually had the same question about isle access.

Are you saying that 62B has someone [i.e. 61A] stepping over them? The marking of the Exit makes it seem like it would not.

Also, any advantages of 63AB over 62AB?

Thanks!
