Think about what encryption should do. Think about what Machine Learning should do. The only thing you can do with ML on encrypted data is show where encryption needs to be improved. Or maybe there is a way to create ML models that produces output which only someone with the correct (private) key can understand.

Yes, that's what the blog post describes how to do.

That's from the post. Is that what you meant by creating a model whose results only the owner of the data can understand?

Precisely. Any encryption that allows an attacker to significantly reason about its underlying plaintext is broken.
