I edited a question, fixing 21 grammatical errors. A moderator rejected this edit, calling it a "minor change":

The same moderator earlier approved a similar edit with only a handful of grammatical changes:
https://webmasters.stackexchange.com/review/suggested-edits/47425
My question is this: Why is the first one a "minor change" worthy of rejection whereas the second edit is acceptable? What exactly is the standard?
