Anybody heard of this technique? It seems to be a little like an implication chain of some sort, but I can't find may details about it. It looks like some sort of forcing chain analysis, but restricted to two rows...

Hmm, I read it as a somewhat restricted version of tabling, looking only at two rows at any given time. I suppose it's not T&E because it considers all the possibilities, rather than just 'try and see if it works'.
This could be a useful technique, as it'll generate quite a small amount of comparisons per pair of rows considered, with only 6 * 9 * 2 pairs of rows/columns to check, so it could shortcut the requirement for tabling.
It feels like a level 3 technique, somewhere before forcing chains.
