Your bloodline is extraordinarily complex. Choose up to three of
the sorcerous gift spells granted by your secondary bloodline.
You add these spells to your spell repertoire, heightened to the
highest rank of spells you can cast or to the highest rank they
can be heightened to that is lower than the highest rank of
spells you can cast. You cast these spells as the tradition from
your primary bloodline
Is there a reason why they would not? They are Bloodline spells that get added to your repertoire. I don't see a reason to not treat them as bloodline spells in every way.
