To me that connotation is actually spot on, in a good way. The Victory in Europe Day celebratory kiss photo happened 68 years ago, but it is so iconic a symbol of success after great struggle that I like it's use in this cartoon. Sure, the posture and act were sexist by today's standard, but in the day, that was the Hollywood Movie Romance kiss, and the actual man and woman were strangers to each other just goofing it up out of excitement and happiness. Here's a re-enactment, with the two original kissers reunited, sharing a more subdued display of affection.
