Those are all the bandwagoners that jumped on when they won their first Super Bowl. You couldn't hit a Niner fan with a nuclear weapon before that.
My favorite part of that play was when Goodwin turned (at about the 20 yard line), realized where the ball was going, and signaled touchdown while the ball was still in the air. That's confidence in your OC, the offense you're running, and the other guys on the field with you.
