I've noticed this on some videos too.
My theory is that when folk download YouTube videos that they don't own and then re-upload them to their own channels, they horizontally flip either
the whole video, or portions of them, in order to try and skirt the /algorithms/code/I have no idea/ that searches for duplicate uploads and potential
copy right infringements.
Like I say though, this is just a theory,
