There are a surprising number of similarities between J.R.R. Tolkien and A.E. Housman, apparently.
It's very easy to find similarities between any two thinkers or writers. Usually the most relevant similarity, when it comes to articles like this one, is that the author of the article is a big fan of both of them.
I could write a long article drawing parallels between Keith Waterhouse and G.K. Chesterton. But all it would mean is that I like both of them, I've read a lot of both of them, and I've persuaded myself that they have greater affinities than they perhaps do.
Is it worth getting exercised about this? Maybe not. But it's flabby thinking. It's like the many articles by Catholics which seek to find spiritual depth in Bob Dylan or the Sopranos or whatever else they happen to be a fan of.
