Can you cite cases where you've seen that happen? You don't even need links; if you have the topic and the rough time these things happened, we can go find them in the Wikipedia backlog.
short version, some old french dude wrote a book/theory on french sauces, original french cookbook mentioned mayonaise as the "mother sauce", but during translation from french to english this was changed to Hollandaise, alex found the original book, fixed the wikipedia entry, and stuff got reverted because the english books didnt mention mayo... then a whole bunch of edits from both sides fixed and unfixed things
