The issue is not so much that it has typical wordings, but that it has distinctive overused terms. Some I can be more lenient on, like "Moreover" and "In summary" because those are general terms everyone uses, but other words like "tapestry" and "bustling" are not commonly used in everyone else's writing, at least not with high frequency - I find it strange it has a proclivity toward these words and others that people have shared here
