Basically, in audio recording if you have two similar but slightly different takes, it adds sparkle to the sound, it makes it seem bigger. Similarly with these sorts of tik tok dancers (to me) it has a similar impact, but visually instead of audibly.
Got an example? Don’t get what you’re talking about. Thanks.

Thinking about it more, I probably should have said “doubling” for two dancers, and “chorus” for more.
In any case for visual doubling, something like this: https://youtube.com/shorts/ZBgeuMJA3vA?si=MPa6AG6q-xw0cutC
For aural doubling here’s an example (not great but first passable example I found) https://youtu.be/kFaaGwAsGt4?si=mfjHIl5PtufoYriK&t=42
