I can think of a possible explanation, but it's a bit of a stretch.
The URL that Fred landed on - http://www.youtube.com/user/copperleaves - is present as a link on the Tomboyish Girl page - in the attribution of Copperleaves's comment.
It might be that Fred clicked a second time while the page was loading, and by chance had his mouse pointer exactly over the copperleaves link at the time, so that the computer acted on the click and jumped to the next page the instant the first page had been rendered.
If this is the case I am jolly impressed by (1) the size of Fred's screen - on my MacBook I have to scroll down to the link - and (2) the speed of his processor and internet connection that he did not see the Tomboyish Girl page flash by on the way to the Copperleaves page. Either that or Fred glanced away for a moment.
