not if you reroute one hose back into the head. look at it this way:

you got the number 11 (the two heater hoses)
you delete one hose, so now you have the number 1 (one heater hose)
then you make the letter U (rerouting the hose back into the head)

you understand or did i just confuse you more? i know some people are visual learners...
