You should always upload the GPX trace "manually" to the server. It
helps others as well and serves as a sort-of "proof" that you really
were surveying.

JOSM does no GPX uploading at all.

All OSM data (not GPX data) gets rendered from time to time on mapnik
and osmarender map layers. (with the exception of a few features that
would clutter the map, but the main thing is, they are in the database
ready to be used by whatever application might make use of them)

Basically when JOSM has uploaded it's data it is in the db, ready to use
immediately. Renderers are a bit slow in making use of it.

Why would you want to duplicate the information from JOSM as GPX?
Besides the fact that the server will not import it anyway because there
are no timestamps on the GPX.
