They can't.
Castrum is the first lvl 50 duty. No player that already did it will queue again for it. That's why they implemented the roulette. So that the queue time is shorter for new players.
Please reread the line and take note of the last part. The idea is to turn it into a solo instance. People have hated running these two dungeons over and over again for years anyways, skippable cutscenes or not.
