The goal of a romanization isn't always to represent the pronunciation in English. They may have other goals, like a one-to-one mapping of letters between alphabets or something. English doesn't pronounce 'q' like 'ch' or 'c' like 'ts' but that's more or less what they represent in pinyin. So I agree you are right about the pronunciation. I just don't think the article claimed they were spelling it phonetically for English.
