I’d say you are correct.
After Reagan was president he was the guest speaker at a business conference at a country club I worked at. Everyone was outside and I had nothing to do so I went in to pick up empties in the ladies bridge rooms. The one I was in had a French door that went outside by a side driveway. I was picking up glasses when all of a sudden the door burst open and 2 guys swept into the room and one backed me up against the wall with his arm. It was Secret Service clearing the way for Ronald Reagan.
I’m sure they don’t let anyone near Obama on his ‘outings’ with the public nearby.
