A. It's mostly because of the creation of a Another Rider in the year the Kamen Rider debuted. E.g. Another OOO is created in 2010, the year OOO debuts, meaning OOO's history and powers were erased.

B. It's shown that if a Another Rider is not created in the debut year of the Kamen Rider they're based off, it doesn't remove their history and powers. E.g. Another Blade was made in 2019 instead of 2004, meaning Blade and Chalice kept their history and powers before Another Blade took the latter and it was "purified" into the Blade and Chalice Ridewatches.

C. The activation and proper use of a Legend Rider's Ridewatch also takes their history and powers. Since Sougo hasn't used (except for Faiz & Kuuga) the majority of the Phase 1 Heisei Era Kamen Rider's Ridewatches, their history hasn't been changed. Although I assume this only happens if A happens since Sougo uses the Ryuki Ridewatch in the Decade Ridewatch but Shinji is implied to have at least kept his memories even after its "activation".
