In fact you are correct.  setup.log.full contains:
2004/02/03 22:59:17 Uninstalling man
...
rmdir C:\cygwin/var/cache/man
rmdir C:\cygwin/var/cache
rmdir C:\cygwin/var

Indeed, calling rmdir on a junction point will remove it, I suppose 
since there's an empty placeholder which gets removed.

Reasonably good advice.  But it's possible that this should be 
considered a bug: uninstalling man shouldn't even try to get rid of var, 
perhaps?
