It shouldn't -- if you're not using topic mode, the group sorting is
drawn from `gnus-group-list'. And when you save->shutdown->restart Gnus,
`gnus-group-list' sorts `gnus-newsrc-alist', which gets written to file,
and on restart it is used to reconstruct the sort order for
`gnus-newsrc-alist'.

Can you tell me what the erroneous behaviour is, and also what "this"
refers to?
