Finite Factored Sets: Conditional Orthogonality

I think a subpartition of S can be thought of as a partial function on S, or equivalently, a variable on S that has the possible value "Null"/"undefined".

Finite Factored Sets: Orthogonality and Time

Can't you define  for any set  of partitions of , rather than  w.r.t. a specific factorization , simply as  iff ? If so, it would seem to me to be clearer to define  that way (i.e. make 7 rather than 2 from proposition 10 the definition), and then basically proposition 10 says "if  is a subset of factors of a partition then here are a set of equivalent definitions in terms of chimera". Also I would guess that proposition 11 is still true for  rather than just for , though I haven't checked that 11.6 would still work, but it seems like it should.
