I think there are 2 ways to look at this.
1. If you are working on strictly getting PADI AOW certification, the deep dive (adventure dive) most likely is not going to cover multi level dive planning unless you have a great instructor willing to spend time with you. The deep dive is only 1 of 5 adventure dives you would complete for AOW. Will just say depending on where you take an AOW course, chances are it will work more like, read the section in the book on the adventure dive you're working on, complete some questions, get quizzed, discuss it with an instructor, and then complete the dive.
2. The Deep Diver specialty course in PADI has 4 required dives. Multi level dive planning is not specifically mentioned as one of the things you learn. Some other instructors may help you out here as to whether multi level planning may be included or give you some suggestions - like
@tursiops has done. Just so you know as you decide what training you're actually looking for, the first of these 4 required deep dives can be applied to getting your AOW certification.
