Once, we both checked in at T-24 and one of us scored A-35ish, and the other was B-02. Probably clicked "Check-in" within a second of one another, while next to each other on the same WiFi network. Still don't know how that worked out...
That may simply be the breaks. A fair number of people check in at exactly T-24. Some of them use automated scripts or other means. Having 5-6 people between two check-ins is not out of the question. But the difference between A-30 and B-2 is substantial, with Family boarding between the them. A-35 would often even be outside the range of pre-allocated seats.
SEB may account for it but it's not really that frequent.
