Agree with the logic though I'm not aware of any adverse effects with both arrangements at our sites.  Configuration seems  to depend on installation company if not specifically specified.  

We have a softener before GAC set up with average chlorines of 0.3ppm over last 2 years with no adverse effects on softener.  

We have a GAC - Softener - GAC set up at several sites.  We did see micro issues at one site but that was after about 16 years of use.  Other sites with similar are fine

We have a new site with an organic scavenger first in line.  That also removes chlorine below recommended levels but, being fairly new, to early to comment.

A question I don't know the answer to - would bacteria that proliferate in water systems survive the brine backwashes of the softener?
