I don’t think anyone (at least involved with culinary arts in any way beyond casual) thought it did. Like how pizza isn’t Italian, Chinese food isn’t Chinese, Mexican food isn’t Mexican, and so on. It’s a flavour someone made in the spirit of another place and everyone just kinda accepts that’s what it is, but they know deep down it’s not really what food from that place is like. Doesn’t mean the flavour is any less delicious, it’s just not geographically accurate. Most food falsely attributed to a region is more flavourful and bold than the food from the actual place. Like it’s inspired by the place or something.

It’s like when Americans started saying “French fries are now called Freedom Fries” and the French said “what you call French Fries are actually Belgian.” A lot of “French” food isn’t really French, either. Referring to chips.
