Daf Yomi - Yoma 58 - Chidush regarding Parshas Shekalim

If Parshas Hachodesh and Parshas Shekalim come out concurrently, the halacha is to read Hachodesh first based on the rule that whichever is more frequent takes precedence. Rav Tzvi Pesach Frank brings a proof from a Tosfos on daf 33 that the rule of אין מעבירין takes preference over the rule of תדיר קודם. Therefore, he posits, that if it would be on the week of Parshas Tetzaveh, which the subsuquent parsha is Ki Sisa (which is the parsha we lain for Shekalim), then we would read Shekalim first based on the rule of אין מעבירין.

I wonder if this is true only if you are laining from one sefer or does he mean even if there would be different seforim?
