Why aren’t objects bent in videos where the frequency of said objects is the same as the camera shutter speed?

The title won’t make sense if I don’t explain as I barely understand the basics. I have recently learned about the rolling shutter effect from this video:

I have seen several posts here on reddit illustrating what happens when the camera shutter is the same as for example the blades of a helicopter. I get that the blades appear to not move but why I don’t get is why the blades aren’t frozen and also bent as seen in the rolling shutter effect.

Example of helicopter blades for example:

There’s definitely some video artifacts similar to this. Like when helicopter blades, fans, and car wheels can appear to be turning backwards at certain speeds.
