Spell Matrices and Multi-Discipline

[Neverbourne]

Ok, I know the caps for types of spell matrices (5/4/3/2) when using versatility or multiple disciplines, but my question focuses on that single spell matrix that every magician gets as a discipline talent at first circle. Were I to add another magician discipline:

1) Does my previous discipline spell matrix become a discipline talent for the new discipline?
2) Does one of my talent option spell matrices become a discipline talent for the new discipline?
3) Or do I get an entirely new discipline spell matrix for the new discipline (so long as I'm still below the maximum allowed matrices)?.

It's #1.
Treat it as you would any other duplicate talent (e.g. like Karma Ritual).

Thanks arma!
