I don't think it's necessary.
1st • You can combine your videos in any video editor (with FFmpeg command line, any software for almost any device, free websites). We're talking about videos, they are made to combine frames together after all!
2nd • I think there's no reason to send a bunch of videos to prove something. Just because it's enough to send the cleanest one. Mods don't need something more, they won't give longer ban according to that or something else. As well, as you can paste a link in extra information with a comment, that you can show more if it's not enough (again, it's unnecessary, and like the most times you don't need it as well as a mod)
