I suppose the pair of them did surrender to an impulse to embrace and kiss but we don't know anything else about them - they could just be actors posing for a photograph.
After a war, I expect there were plenty of overjoyed couples who thought they may never again see each other and were delighted to do so - as well as those who lost their loved one.
I can't see anything particularly remarkable about the picture - which has somehow been made into a sculpture - but I suppose if nothing else, it's hopeful.
