That's exactly what he meant.  You don't want to cut off more than 50% of the image you took because then quality will suffer.

Are there any circumstances in which resizing gives better detail?

Cropping is not related to resizing.  Cropping means you cut off part of an image. A "100% crop", at least when used in this forum, means a piece of your image without any magnification or resizing.  Resizing means you alter the dimensions of the whole picture. It is usually used when it is not practical to show a full resolution picture.

This is a resized image:

That was the full frame image of a picture that I resized for inserting here.  I can use a different size, if I so wish:

I did not crop this image, I did not cut off any portion of it.  It is the full frame as I captured it.

This is a 100% crop of the image, before I post processed it.

Note: As I am typing this message and inserting images, images look fuzzy.  Hopefully they won't end up this way.
