Mostly, it's reason number 1.

Except for highway=unclassified and highway=residential, names aren't 
repeated along the length of a road. So if the road is much longer than 
the extent you can see on your screen, it's likely you will not see the 
name.

As for why this is so, I don't know. Either it's by design, or just 
hasn't been added to the style yet. I'll leave question that to Steve 
Chilton.
