He has a different set of experiences in the sense he is now living in a time/world where many people are open about their sexuality. It will change how he feels/reacts to feelings he has. Back when he was young he wouldn't considering anything he felt to be unusual, or realise what a glance or a thought meant. No-one said men loved men when he grew up, so it's a totally different world (and creates different realisations). They WERE the same person with the same experiences, but then it all changed when Beast brought 05 Bobby forward in time, to a world he doesn't need to fear being himself.
