That sentence is my fault. I've been sitting on a patch for about a
week that fixes it which I was going to submit after 2.20.0, but since
you're fixing this text up right now, I guess putting these two patches
together makes sense. I've rebased it on top of your commit and provided
it below.

Subject: [PATCH] git-rebase.txt: update note about directory rename detection
and am
In commit 6aba117d5cf7 ("am: avoid directory rename detection when
calling recursive merge machinery", 2018-08-29), the git-rebase manpage
probably should have also been updated to note the stronger
incompatibility between git-am and directory rename detection. Update
it now.

+The merge and interactive backends work fine with directory rename
