I think they were likely referring to the behavior and not the choice of shortcut keys. On Windows, alt+tab switches between all open windows across a apps, whereas in macOS, you have separate shortcuts for switching between apps vs windows within the same app. Personally, I find the macOS behavior really irritating and unintuitive, but thankfully there are plenty of apps out there that solve this issue so it's not really a problem.
