Those commands look quite arcane to my eye. In Mercurial we do:
> hg pull --force <project-to-union-merge>
> hg merge
> hg commit

So in a sense you are right, that's exactly the point of contention. However, simple (and hard) things in Git are done in a complicated and non-obvious way, which require you to memorize a bunch of commands and flags which require understanding the internal implementation of git. There are much easier and intuitive ways of doing version control, and Mercurial proves it.
As a side note, I can't be bothered to look it up right now but iirc even Torvalds said that originally Git's CLI was not actually meant to be used by end users (rather, another abstraction layer on top would provide a friendlier approach to version control). But people ended up using it as it was, for various reasons.
But this CANNOT be said about git! For example [1]:

In Git you can merge with an unrelated repository by doing:
> git fetch <project-to-union-merge>
> GIT_INDEX_FILE=.git/tmp-index git-read-tree FETCH_HEAD
> GIT_INDEX_FILE=.git/tmp-index git-checkout-cache -a -u
> git-update-cache --add -- (GIT_INDEX_FILE=.git/tmp-index git-ls-files)
> cp .git/FETCH_HEAD .git/MERGE_HEAD
> git commit
Those commands look quite arcane to my eye. In Mercurial we do:
> hg pull --force <project-to-union-merge>
> hg merge
> hg commit
