UVW weirdness on back of aircraft around Vert Stab bases

While extending the red stripe up to the top of the aircraft as seen in older late High-Vis schemes like that of VF-201 and VF-202 (prepping for F-14A), I noticed some oddities when the definitely straight line in my texture was NOT straight on the back of the aircraft:

 

 

 

I recall some issues with a flipped vertex being reported a loooong time ago, but couldn't remember if this had been reported. While the A model we're getting is supposed to be later than the late 80s timeframe VF-201 wore this scheme apparently into the 90s at least on their CAG bird and even alongside the lo-vis with other line aircraft. It's one of those things many would overlook but once you see it exists, it's hard to ignore, especially after spending a lot of time trying to replicate this squadron.
