The “Restricted” list is different from the “Blocked” list in that restricted users can still view public posts and posts on mutual friends’ pages from the person who blocked them.
Depending on when your friend made their public posts, you might not see a gap here even if you have been restricted.
This doesn’t necessarily mean they’ve restricted you–they may have simply decided to post only public items.
It also might mean that your friend simply deleted their posts.
Even just asking them if your friend has posted recently when you can’t see any account activity from the past month or so will accomplish this goal.
