I dont know. It makes sense, either way there is an imbalance at this point, but the Bills official website has it that way.

And I couldnt find much else, but this:

Unless the NFL is able to weasel an 18th regular season game out of the NFL Players Association (NFLPA) we know the Commanders will play one more road game than home. That team will be the AFC East Division team that finishes in the same positioning as Washington does in the NFC East.
According to early projections, it's likely that team will be either the New York Jets or New England Patriots. Either way, it's an east coast trip, so good for mileage.

Jets home vs NFC East in 2025

For fans, the rewards are more inarguable and straightforward. The 17-game regular season starts this fall, meaning the universally hated preseason shrinks. AFC teams will host nine regular-season home games this season (the NFC goes next season, and they alternate thereafter). The scheduling formula -- teams from opposing conferences that finished in the same place within their divisions the previous season will face off
I do not see anything pointing to the possibility that NFC hosts the AFC again next year for the 17th game.
