I'm not generally a fan of litigating language choices since, well, all words are made up after all. It's easy to be accused of pedantry if you're going to complain about someone misusing mathematical terminology in an orthogonal context (see what I did there?). It's hard to build a compelling soapbox on, "Well actually, that terminology isn't correct..." That being said, I'm a little baffled after reading that article. I suppose the thinking was that the client and server are isomorphic to each other if they're running the same code. As someone who also has a mathematical background I don't think it's very elegant...but it's obviously caught on and it's creative, so I can dig it.
