If you weren't checked in for your next flight, would you even have been allowed to go to the BA gate?
Anyway, for future reference, if you're anywhere airside at OSL, you can always pass landside, completely legally, by going up the stairs behind the seafood bar, between gates E12 and E14. At that point you're in the same long hallway arriving passengers use to get from immigration to baggage claim.
