Mapping two features with the same way seem highly efficient.
That OSM-Carto's software is unable to deal with it, is a long-standing 
weakness & should be rewritten to solve it. However, regrettably those 
involved in the project seem to like using the software's shortcomings 
as an excuse not to sort out problems, so I don't see that happening any 
time soon.
