I don't think it's a convincing narrative that that's what Putin wants, and also that that's something he could reasonably accomplish. But I do hear it often as a powerful narrative to help Ukraine more, and I understand why, but from my point of view it's not very convincing.
At the same time I agree with the sentiment that heavier the losses in Ukraine, the more he will have difficulties in starting similar drama in other countries with large Russian communities.
