I admit I've never tried this so I don't know which policies do or do not apply and how. For things like the play store (which is what I've worked on in the past), only the "primary" account (the one you logged into first) will have access to it so if your secondary account has the play store blocked anyway, you won't be able to use it with that account so it doesn't matter much. I don't know about other policies.
