I can attest this to be true, at least in one circumstance.
2 years ago my buddy and I were scouting in mid August and came upon the same scraping you mentioned. After careful monitoring we found this to be a territorial scrape by "THE" mature buck in the area (on public land.) We made a solid plan and each took stand on travel routes to/from the scrape area. We both saw the monster buck opening morning, evening, and then the next few times we hunted we'd see him off and on, but he was always either just out of range, or not enough light to shoot.
He ended up falling to another hunter's arrow in early November. 13 point with a massive drop tine.
