I can confirm your results.

More refined investigations:
If routing starts on the east half of aa (between two nodes) everything 
is ok with every destination.
If routing starts in the wast half of aa (with the missing end node) and 
destination is N or S then the purple line fills the whole segment. (Not 
starting from current position and going  in the wrong direction, but 
the whole segment!).

I agree, that there in theory should not be needed a node, as there is 
no junction between two streets. Routing works fine without the final 
node, but the drawing algorithm seems to need it.

Latest news:
I've just discovered, that the error has something to do with the zoom 
level!
If I zoom out to 120m then the pink line draws correct.
