Please tell me if this is correct.

That looks right. The pcv system is supposed to draw filtered air from the air cleaner into the cranckcase then out through the pcv valve into the intake to be burned. If the system does not function at 100%, some oil/fumes into the air cleaner will result. I wouldn't worry too much about it unless it's excessive. Do be sure you have good stro g manifold vacuum and an operating pcv valve.
