David Rose Endorsing A Contradiction Of His Own Claim

Note that generalisation increases down strata (not up), Martin & Matthiessen 1991...

The most powerful generalisation is, arguably, that there is a tendency towards generalisation as we move down either the stratal organisation or the rank scale. That is, to put it crudely, a given number of semantic systems is realised by a smaller number of corresponding lexicogrammatical ones; similarly, a given number of lexicogrammatical systems is realised by a smaller number of phonological ones. And the same holds for the rank scale; for example, a given number of clausal systems is realised by a smaller number of verbal group systems. The reason for this state of affairs is easy to see. A stratal descent or a rank descent always entails a generalisation across contexts and this generalisation is reflected in the relatively smaller number of realising systems.

To be clear, here Rose unwittingly provides further evidence against his own previous claim (here) that 

[Halliday's] grammatico-semantic model assumes a bijective or one-to-one relation between LG features and semantic features…
