Not really, if you read between the lines and realize that they are not just claiming fact, but also cause ("men don't want to marry up" vs "women don't want to marry down").
And which one is the cause here? I don't see why anyone wouldn't WANT to marry up.
I'm pretty sure that there are much fewer women in the high status category than men, so these men make the only rational decision (if they don't want to stay alone) - they marry down.
