The code in question is a configuration option for a third-party jquery plugin. There may be better plugins which expose their configuration options differently but I personally think that the benefits of using the library itself outweigh building something entirely from scratch for a more purist interaction. I've worked with some gross libraries before and I think that the benefit of using them outweighs a few comments for obscure settings.
The third party code in question isn't terrible as you can assume it's the resize delay from its name. I think what made it terrible was the fact that since a magic number was used (16) it wasn't as apparent for a reasonable developer to grasp without questioning it. Yes, some people will know that 16 milliseconds equates to around 60 frames per second but I don't think it's reasonable to assume everyone who looks at it will. It was a bad example on my part, however, as with a constant as opposed to a magic number you don't need the comment at all.
The code smell I mentioned was wrapping a third party configuration in a function as a way to limit commenting. I think commented configuration options make it easier for other developer to grasp why something is configured that way -- especially for code that will be minified.
I don't think I explained well enough that the code in question was from a third party interaction, however, so could see how we may be on different wavelengths. I'm also by no means a purist when it comes to comments though so I'm sure we may have opposing views (although I agree with the general idea as you mentioned to annotate why not how/what).
