Cheetah uses some algorithm to establish a similarity score and then auto-comments everything above a certain threshold. They do manual review before taking any punitive action. In this case I only saw it after your edits (sometimes they don't take kindly to edits) but it seemed there is enough difference that you don't need to worry.

It was cheetah that linked to our Complete Overview and not you, but I should mention that it contains many references to how things worked before our automation was released. Always make sure you are referencing the most current material when you research Steem Basic Income.
