I followed all of the other changes but don't understand this one with respect to support for 20.04.
Is this a bug fix of some other behavior?

Other than not understanding this one item, the rest looks good.

This is a change to the front end of the E2E suite that handles configuration injection (via environment variables) into the api model before building out and then testing the cluster.
While integrating the new 20.04-LTS VHD into E2E tests, I noticed that if you pass in an env var to specify the distro value it overwrites all pool distros. We don't actually want to do that as we intentionally test a mixed-distro pool.
You can see the results in the successful test output of the new 20.04 test:

I.e., the control plane is running the env var-configured distro (20.04-LTS VHD), but the pools are running various OS distros that are explicitly configured in the api model.

Ahh! Thanks. Maybe a small comment in the code as it was unclear what it was trying to accomplish in my (naïve) reading of it.
