That's the page I was reading (except I messed up the units). I think it's saying that you have the option of scaling 1px so that it matches a particular angular size, when it makes sense:
"For a CSS device, these dimensions are either anchored (i) by relating the physical units to their physical measurements, or (ii) by relating the pixel unit to the reference pixel ... For such devices it is recommended that the pixel unit refer to the whole number of device pixels that best approximates the reference pixel."
"The reference pixel is the visual angle of one pixel on a device with a pixel density of 96dpi and a distance from the reader of an arm's length. For a nominal arm's length of 28 inches, the visual angle is therefore about 0.0213 degrees."
