[1] The first sentence is misleading because it is not true. Since, by definition, an initiating move occurs earlier in a sequence than a responding move, these classifications do indeed sequence the moves.
[2] The second sentence is misleading because it is not true. For example, sequencing clauses in a clause complex does not require a higher ranking unit. Rank is a model of formal constituency (on strata that have forms). Higher ranks are motivated by having constituents.
[3] The third sentence is misleading because it is not true. The relation between ranks is not realisation, because ranks on a scale are all of the same level of symbolic abstraction. For example, the clause system of TRANSITIVITY is not realised by group functions such as Deictic and Auxiliary.
