It is important to note that output impedance chart varies from 5 milliohms to 50 milliohms, so the effect at worst case of the magnitude and angle of the impedance on the speaker are tiny, so the lower chart with the actual output should give a very good idea of how the amp would perform.
Class D amplifiers have very little phase shift
Too many diagrams to post here, so I just blogged it:

The 20 degrees at 2 kHz argument is bunk.
