Yes, that was the reason. The graph itself was inspired from
a discussion on #revctrl/ on 18 Sep 2006:

you may find more information there. Nathaniel put it like this:

  in monotone, branches are named and stored within a single repo,
  and network operations simply exchange information about new items
  (so my box might tell the server "btw, there are some new
  revisions in this branch and that one") a single branch can have
  multiple heads, if you want to merge you do that as a separate

Again, Nathaniel explained this:

  darcs is like identical to bk/hg/bzr wrt its branch workflow, but
  if you look at their history models, you have darcs vs. everything
  else as by far the biggest split

It took me a while to understand my own graph again:

it's a bad graph anyway. It started out as a chronologic
left-to-right graph, but then that did not work out, so I switched
to something else. The three lines on the bottom are not scales in
that VCS to the right are "more atomic" than those on the left, it's
more a split into atomic vs. non-atomic. The lowest x-axis just
simply separates branching models, and here, SVK, darks,
bk/git/hg/bzr and monotone differ a lot.

I guess darcs is also split from the others because its author
basically did it himself, while bzr and hg and git and so on all
stem from a common theory. darcs is very innovative in that sense
and has been very influential for the others. However, I also find
it not to scale at all. YMMV.
