Oh yes it does! See
- both show the same Karlsruhe roundabout, one with JOSM set to
EPSG4236, one with JOSM set to Mercator. The "align in circle" will
always create something that is a circle on screen, i.e. if I choose to
work with EPSG4326 in JOSM and use "align nodes in circle", then a map
created in the Mercator projection, e.g. our slippy maps, will show an
oval that is much higher than it is wide.
As long as I leave JOSM set to Mercator it works fine, so it's not
really a big issue.
