I'm not sure why that matters. The way represents several parallel 
tracks without making any statement about whether one can cross them. 
Anyone using the data should assume implicitly that "changing lanes" 
doesn't make sense on a railway, just as real-world automobile routing 
algorithms don't tell cars to drive laterally across the roadway just 
because that entire surface is available for vehicle use. Mapping the 
transport network is about describing useful travel paths, not about 
describing all possible ways a vehicle can physically move.

With that said, I'd love a link to the previous discussion if you have 
it; all I was able to discern from the wiki was that we're really 
inconsistent.
