It is on the line, but sometimes up to 1km wrong position - though 
mostly 100-200m away. It this is a bug that can be fixed - than 
disregard my comment to drop the support at resolution 24, but I 
remember Mark Button (hey, I miss you and your great coding BTW), 
writing that it is inherent to the function itself - though I don't 
understand why - to me it should not matter whether a road was a single 
part in OSM or two parts and merged (but on single part roads this bug 
is not showing up, so likely it can be fixed...).
