No, the event horizon is not really a place, and you're not crossing it at the same time as anyone else, you're just crossing it at the same time as you are seeing light from other people who crossed it before you.
It’s not really much different from saying you crossed any other subset of spacetime traced out by the world lines of photons at the same time as you would be able to observe some of those photons, and/or emit some photons yourself that were confined to that subset of spacetime.
