Yes, this is correct, and a change to the documentation has been pushed.
But even better, you point out a problem in autobeaming, and the default
rules get fixed. You can either wait until 2.13.5 comes out, or you can
download a new copy of scm/beam-settings.scm from
http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=blob_plain;f=scm/auto-b
eam.scm;hb=6dbcbed04394fa63107265c9373231d10ec38cfd
and save it in place of your current scm/beam-settings.scm. Then things
should work properly.
HTH,
Carl
