From the FIBA eligibility rules

A national team participating in a Competition of FIBA may have only one player on
its team who has acquired the legal nationality of that country by naturalisation or by
any other means after having reached the age of sixteen.

The one naturalised player allowed needn't have any roots to the country he/she is playing for so long as the citizenship requirements are met, and the player hasn't played for any other country previously. This, I presume would be the case with Page, like Hammon (and later Prince) did for the Russians, and Lindsey Harding is doing for Belarus this tournament.
