The latter.  The distance between two points are distorted.  Also,
coordinates in lat/lon do not mark the location they should mark.  I
ran into a problem with OSM trying to pinpoint the GPS location of
DebConf7 in Edinburgh (55.94508 -3.18867), the coordinate in Google
Maps was correct, while the same coordinate in OSM was way off.
