AFAICS, that is the expected result.  The modem is connected and you do
not disconnect, so "start-network" has no effect.

If you do not want "autoconnect" then you should not include it with the
"start-network" request.

If "--set-autoconnect disabled" does not work as expected, then please
try "--stop-network --autoconnect".  This should both stop the current
session and disable autoconnect for future sessions.  Until you enable
it again with "--start-network --autoconnect".  Just don't do that if
you don't want autoconnect...

I haven't seen any such issues with the Qualcomm based modems. They seem
to deal pretty well with the difference between their data bearers and
the initial default bearer.
