This is incorrect. Iso and neo are the 2 prefixes that are included when alphabetizing substituents.

This one is tricky, so you take iso- into account when alphabetizing the substituents, but not di-. Therefore, you have to think of it as if dimethyl starts with an M and isopropyl starts with an I, which is why isopropyl is first.
