Forks look quite track-like so my first thought is that they're converted track bikes.
But bosses for shifters/bottles/cables make that less likely...
as @midlife said, rear facing dropouts were a thing on 80's TT bikes with super tight clearances but these don't look like retro-TT exotica - on balance I'd want to be convinced that they're not meticulously converted track bikes.
Thanks! Yeah on second inspection with that website as reference, that club logo on the tubes is all wrong
