Neither is showing you made a merge.  If you try gitk (or "git log
--oneline --graph"), you'll see that a merge does not result in a
single strand of pearls like the above.

I think your merge is working perfectly correctly, without
butchering the order each branch had its commits, and adding a
single merge commit 'M' that is a child of the commits at the tip of
these two branches.  It's just the order of commits you see when you
tell the tool to show them linearly (e.g. "log" without "--graph").

There are "--topo-order" etc. options that you can influence the
display order of the "log" output.
