Do you have a different way or reading this (from the AFL 3.0):
"Licensor agrees to provide a machine-readable copy of the Source Code
of the Original Work along with each copy of the Original Work that
Licensor distributes. Licensor reserves the right to satisfy this
obligation by placing a machine-readable copy of the Source Code in an
information repository reasonably calculated to permit inexpensive and
convenient access by You for as long as Licensor continues to
distribute the Original Work."

It looks like the obligation to distribute the source *goes away* at
modification but is there by default.

Reread the section on external deployment and the source grant
together.  If you deploy the unmodified work so that users outside
your organization may access it, you have to provide them the source.
Once you modify it, this requirement goes away.
