Yes, they do. The Balance intensive is for beginner and intermediate handbalancers, and so is for those training the Push, Keep Pushing and Press programs. As such, it will cover, and expand upon, the material of those three programs.
The Advance intensive for advanced handbalancers, the corresponding program is the Push Harder program for the one-arm handstand. Practitioners will also be likely to be working on the Stalder section of the Press program, and begin looking at the Mexican Handstand through Bend.
