That is indeed true. Only issue I can see is the copycat community might not outgrow the older community. And I think people tend to gravitate towards the larger community if there are multiples of them. Especially newer users who won't know of the power tripping mods and will just assume it's an ordinary community. But let's hope new users joining the Fediverse have better critical thinking skills and start asking questions if they see a community with a strong and active copycat community.
