Permesso C Familiare?

Hello all,

Bit of a silly question, but I just received my C Permit card in the mail (so glad they've done away with those silly plastic wallets).

Interestingly, below the "tipo di permesso" it states: Permesso C familiare

I assume this is in reference to the fact that I am married to a Swiss citizen though I wonder why "familiare" is included here? Does it have any bearing at all?

Family reunification permit - that’s how you qualified for it.
