Jeff, one (an AHJ, not me) could argue that this figure doesn't apply since there's already figure 8.6.5.1.2(c)
I personally feel that the difference between the soffit that goes all the way up (as in 8.6.5.1.2c) vs the one shown in A.8.6.5.1.2 is ridiculous, but at the end of the day, the latter is only in the appendix, not the main body of the code.
