The mother of Fernaõ Mendes de Bragança was allegedly a Georgian royal. How did a Georgian royal end up marrying a Portuguese noble in that era?

I saw this genealogy on r/AncientRome.

One of the characters that Redditor claims to be descended from is Fernaõ Mendes de Bragança. Allegedly, Fernaõ's mother Ardzruri Artsruni is a Georgian royal. She herself is allegedly descended from Armenian royalty, Bosporan royalty, Thracian royalty and Mark Antony.

How did a Georgian royal end up marrying a Portuguese noble? I can't see any political advantage in this, since she would be marrying down, and the marriage alliance wouldn't be useful considering how far Portugal is from Georgia.

There's absolutely no evidence for this whatsoever and it seems pretty clear to me that the Braganza dynasty was just trying to legitimize itself (since they were descended from a bastard son of John I of Portugal). I'll have to crosspost this on the AncientRome sub...
