It's probably some vestige of sexism, really. One should stand up for the weak against the strong, and men are seen as strong and women as weak in general. It's not fair, and if it leads to something like this in a more serious scenario where it's not just actors then it's something that needs to change.
On the other hand, stunt videos like this can sometimes be one-offs and make effects some more exaggerated. A similar sort of video, about bike thieving in America by man, woman, and young black teenager, showed similar differences in behaviour (some people even helped the woman to "steal" the bike), but at least some of this might have been down to the language the actors used (for example the teenager was asked if it was his bike, and he replied "It's going to be"). So I'd say we should be wary of taking this video totally seriously.
