The meaning of the new cover (U.S. version)

I don't mean to be daft, but the cover has been intriguing me. If you
look at it in full-length (Border's is offering a poster of this), one
notices that Harry and (what appears to be) Voldemort are not facing
each other, as if in battle. Instead, they almost appear to be doing
something TOGETHER, ALMOST COOPERATIVELY. It appears they are trying
to ward off something or summon something? Perhaps one is trying to
summon, the other ward off? My initial glance had me thinking these
stray thoughts...wondering of others' reactions...
