User blog comment:Koteitan/Purely mathematical definition of BMS/@comment-30754445-20181123092422/@comment-30846880-20181123143112

@PsiCubed2 Is Koteitan's definition equivalent to my uncorrected version for standard sequences (that is: for sequences that can be arrived at from (0,0,0)(1,1,1) in either version?).

If Only the sequences which come from (0,0,0)(1,1,1), that means, if we consider only pair sequence system, I think yours and BM4 are the same.

Also, I think they differ in the BMS with 3 and more rows (I posted your article about that). When we consider about only 2-rows BM4 sees only top row to deside bad root r. That is the same as yours.
