yes it does.

Writer's document model implenents com.sun.star.drawing.XDrawPageSupplier
http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/Text/Shape_Objects_in_Text#Drawing_Shapes
It seems someone deprecated
http://api.openoffice.org/docs/common/ref/com/sun/star/drawing/XDrawPageSupplier.html
but that's wrong, this is the only way in Writer to access the DrawPage (the
reason seems to be that there was a time when in Calc one accessed a single
sheet's DrawPage via this interface - this seems to tell the fact that the
only service supporting this interface is ::com::sun::star::sheet::Spreadsheet
http://api.openoffice.org/docs/common/ref/com/sun/star/drawing/XDrawPageSupplier-
xref.html#SupportingServices)

@Sebastian:
this is the "old" Develper's Guide. You must read the "new" version on the
Wiki
http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/Drawings/Grouping%2C_Combining_and_Binding

both method for grouping shapes described there work in Writer... well, only
the first one does the job as expected. The code attached [CC you, as I'm not
sure it will pass this list, in the API list it usually does] shows them both
parallel in Writer and Draw.
