If I wanted to interpret this in a paranoiac way, I would say that's because the author of the PR isn't apologetic at all, and in fact is quite fine with forcing a PR through the maintainers without their consent.
Remember the old adage - never attribute to malice that which is adequately explained by stupidity. Hanlon's Razor, I believe it was. And here, by "stupidity," I just mean the author didn't think about that. Too often people are willing to attribute sinister meaning to what, in reality, was just a mistake.
Since I can't read people's mind, a good trick that I learned is to derive intent from actions. Removing a merged PR is easy, especially when you can force merge one in the first place.

Edit: the PR was removed by the current maintainer.
