IIUC this suggested comment is implying that the running status is
*only* preserved when the failover option is true. But AFAIK that is
not correct. e.g. I hacked the test to keep subscription regress_sub2
as ENABLED but the result after the upgrade was subenabled/subfailover
= t/f, not f/f.

OK. Now using your suggested 2nd sentence:

+# The subscription's running status and failover option should be preserved
+# in the upgraded instance. So regress_sub1 should still have
subenabled,subfailover
+# set to true, while regress_sub2 should have both set to false.

I also tweaked some other nearby comments/messages which did not
mention the 'failover' preservation.
