Totally surprised I have to say.

The obvious question then is:
How dark are the LK and LLK actually ?

The most likely reason probably is:
Epson kept as much of its basic color driver possible in the Advanced 
B&W part to make color toning easier. The composite grey is there as a 
base to shift to the sepia etc without changing the density per grey 
step as a result. Simpler than linearising every possible color tone 
combination. A kind of 10% composite grey cover over the entire range 
and by that the 10% at the bottom can't have LLK. It will not influence 
the fade quality much but time will tell how consistent the printer is 
to keep crossovers away.
