...they did? Which one are you referring to?

I think he meant Richard de la Pole, who was planned to be married to Dorothea of Denmark before he was killed at Pavia.
But it was not that Dorothea, who was Charles V's niece indeed:

But her cousin, OTL Duchess of Prussia:

As @Jan Olbracht said but I mistaken Dorotheas, but still later Dorothea was a royal princess.

If Alfonso survived he would marry Juana la Beltraneja as Henry IV wished but his sister Isabella would still marry Ferdinand II of Aragon as that match was long planned and long desired by both sides (Isabella&Alfonso on one side and Juan&Fernando on the other one). Alfonso would still need support from Aragon and marrying Isabella in Portugal (or France) would be a waste when the heir of Aragon is available and willing
