I do not think it is the same thing at all. The patent describes a channel cross-feed while this is a delay inserted between the inner and outer arrays of midrange drivers in each speaker. This will have some effect on what the listener hears but the justification is, imho, simplistic and has nothing to do with head dimensions but, perhaps, more with the dimensions of the speakers themselves.
The delay between the ears at the head is equal to the thickness of the head (let's say .8ms for a big head) but only if the source(s) are entirely lateral and is zero if the source is directly in front. Normal stereo speakers are somewhere in-between and no single delay can fit all speaker distances and angles. Besides, with his laterally-opposed midranges, most of the energy from them will be dominated by reflected energy and the treble drivers (and, to a lesser extent, the inner midranges) will dominate the direct radiation. However, for such treble, localization relies more on intensity (and HRTF) than on timing. I did sit through Carver's entire presentation in NYC (with a little discomfort).
