Unlike men usually assume women will step aside, but not other men? In that case, yeah, she didn't "walk like a men" by that definition but is that the important thing?
If you're in a busy street you
don't have time to make any assumptions. You get passed one person and there's another right behind them. You might have to navigate passed thousands of people a day in a busy city, and you have a split second to make each decision. Whether they're male or female doesn't factor into the equation. If there's a fat woman, I'm going to navigate around her more than a skinny man, purely based on the size of the target.
When I'm walking down the street in a dense crowd the gender of the other people is the last thing I'm thinking about, they're just a mass of undifferentiated people. That's kind of the point, you're not seeing them as individuals, or grouping them by gender, their just faceless obstacles to be avoided. You're thinking about size, speed and location relative to yourself, and you need to be able to simultaneously do this for a dozen or more other people at a time. There just isn't any time in that situation to make differential assessments of each person's likelihood of moving out of the way, based on ithe gender of the person. That would take let's say half a second, and you don't have half a second to make the decision.
