Its because one tensioner is upside down compared to the other, so on one side the adjuster foot moves on the top and on the other side it moves on the bottom. 15 links on the tensioning foot, 16 links on the adjusting foot. The head that has 15 links between marks has 16 teeth underneath, and vice versa.
Its all done like that so they can have one casting for both heads with machining differences determining which is which. Thats why one tensioner is on the front and one is on the back - the heads are basically the same part flipped 180 degrees, rather than mirror images of each other.
