2012 UPC and cleanouts

[memyselfandI]

So I have a plumber arguing with me that a cleanout is not required at the end of a drain line, only at changes of direction more than 135 degrees. I feel this is pretty obvious based on my reading of the code (that a cleanout is required at the end of each line and also at every 100' or fraction thereof after), but he's adamant. Am I misreading something? This is not a special case o being less than 5' or anything.

(UPC 707.4, ex.4)
• Required at each aggregate horizontal change of direction exceeding 135 degrees. (UPC 707.4)

Maybe it's the way I say it but plumbers seldom argue about the need for cleanouts.

"plumber"? is he licensed? Is this a "fixed price" contract issue?
