How about rewording it more extensively? It doesn't read great IMO.
I would use something like
# In the upgraded instance, the running status and failover option of the
# subscription with the failover option should have been preserved; the other
# should not.
# So regress_sub1 should still have subenabled,subfailover set to true,
# while regress_sub2 should have both set to false.
I think the symmetry between the two lines confuses more than helps.
It's not a huge thing but since we're editing anyway, why not?
