I would advise against such generalisations - it depends so much on the
circumstances and the mapper in question. OSM prefers objective data.
This one has a difference of only 40m. Optically/subjectively it's
pretty much dead level. I have done it many times.

Despite the minimal difference the website does indicate that one side
is the "top station" and the other side is the "bottom station", but
that's probably not a valid source. Anyway, suppose they were both at
exactly the same altitude. What's the intrinsic difference between top
station and bottom station? The location of the drive motors perhaps?
That would be an objective attribute that we could put into OSM
(motor=yes/no?)
