This is all a little pointless.
Is he definitely committed to us? Well, he has only played for us so that demonstrates commitment.
Is he tied down to us? No, he remains eligible for more countries than a lot of people have been to.
Of course he is going to be referred to as Irish and if they're giving him a flag at his unveiling then of course it's going to be an Irish one. That all means something. You said it "doesn't necessarily mean anything."
Simple fact of the matter is that that like any player that qualifies for more than one country, they are not tied to us until they are.
If he kicks on here, he'll get a call up. Who knows what he thinks about the other countries - maybe he feels Spanish for growing up in Spain and if they reckon he's good enough for a cap before we do then that's a threat but that didn't occur at underage level so the chances are low.
I'm typing longer responses than the questions, I know.
