Appearances only. It's more of a mismanagement system. It'd be better if they didn't even pretend to try.

I'd be ecstatic if there were exposed tines and I could just wrap the power cord. Like a typical vacuum cleaner.

But it's a recessed wind up area, and you really have to force the cable in, precisely to fully hide the cable. If you don't, there's a pig tail remainder. In which case, why bother at all?

There might be some other reason...just speaking generally since I don't know which model you're talking about, but maybe you can't do what you want because of some factor, like minimum bend radius of the power cable.
