Personally, I view it as "David changed timeline" situation, which begins with the first scene of Legion (TV series) Season 3 7. Future Syd, Kerry, Cary, David and Switch and Earth-TRN620 travel into the past, interact with past Gabrielle, Charles and Farouk. Then Future Farouk joins them, a confrontation ensures. Most importantly, the aftermath of Charles encounter with Farouk is changed from what explicitly was shown on-screen in Legion (TV series) Season 3 3. As Switch becomes the four-dimension-being-or-something, she states that the timeline will now be different, and future characters fade out from existence, because *this* time-travel apparently does run on Back to the Future rules.

The way Switch's time-travel works, she seems to undo the future every time she travels into the past, becoming the only person to remember how things were, as shown in Legion (TV series) Season 3 1. However, in every previous on-screen case she was only shown to undo a few minutes worth of time, so I personally don't think that warrants a bunch of new TRN, unlike the major change in the last two episodes.
