...the 801M Series II spec states exactly as what you posted regarding crossover alignments. However...........in the discussion section of the 801 users manual preceding spec tabulation: "It should be noted that the loudspeaker may be used perfectly satisfactory without this additional [BAF] filter giving the system a fourth order Bessel alignment." In the case of the 801, the BAF is actually a S&K 2nd order HP filter with fc~20Hz and Q=2. All this is consistent with 4th order Bessel w/o BAF and 6th order Butterworth w/BAF. I assume, maybe incorrectly, that the 802 is same basic design w/diff fc.
