From logic you seem to be right, but...

Image you have oo.o installed, but not oo.o-g. The first dependency will 
be satisfied, but the second will automatically install you g-o. You 
need to reverse the second dependency:
gnome-office | openoffice.org, openoffice.org-gnome | gnome-office

This will install you oo.o-g if you allready had oo.o installed and 
install you g-o otherwise.

Nevertheless I consider this far less obvious than 'g-o | oo.o + oo.o-g'.

Have a nice day, too. ;)
