If you're merely correcting grammar, alphabetizing, fixing coding, or something similar, then the edit is minor, but if you are adding or removing any content at all, even a single word which changes the meaning of the previously established content, then it's a significant edit, even if it's relatively small in scale.

The reason it matters how it's marked is because the various markings display differently depending upon our settings, so edits which need review by the database's staff are sometimes less noticeable and potentially slip through the peer review cracks if marked improperly.
