item already has the maximum number of socket links question

How is it possible to have 6 links on a 6 socket item? As far as I can count you will have max of 5 links on a 6 socket item, if your goal is to only connect once with each socket.

In wiki explaining about how socket and links work there is a picture to show how a fully linked item connect on a 6 socket item and there is a max number of 5 links as far as I can count. Use <control+F> to jump "Order" in link below. Count the number of arrow showing path/links. I can only see five links on that picture.

Number of sockets: n

Number of links: (n-1)
_____
Number of socket: 1S give O link; 2S give 1 link; 3S give 2; 3S give 2 links; 4S give 3 links; 5S give 4 links and finally 6S give 5 links.
