Hi Neil
Understood but are you overlooking the earlier rule? If I am understanding this correctly per the diagrams, the 3rd move involves the 2 deep block of Pike moving forward and contacting the 4 deep block of Pike. In this case the 2 deep block of Pike is a column entering a gap and has contacted an enemy element or group. So under the rule I quoted, the 4 deep block must conform. Note in the rule quoted that the first half of the sentence mentions front edge whereas the second half (which is the part that is relevant) only mentions 'contact'. I presume this is not being applied given a corner is not part of an edge? Whilst the actual rule is under the heading 'front edge' the 2nd bullet point only mentions contact.
If you don't want to apply this rule (because of the corner vs edge thing), then the rule at the top of the page could kick in, in that friendly elements are preventing the 2 deep block of Pike from lining up so the move is cancelled. Alternatively, if I were the owner of the Blue Pike, and my opponent was going to be bloody-minded about not conforming then I would insist the 4 deep Pike block had to fight both of the 2 deep blocks of Pike given it should be fighting against at least one overlap.

FWIW, I agree with Andrew's interp. The side-headings in the first section of p.33 are about how the elements end up, not about how they actually make contact. So, when in diagram 3 the 2-deep blues advance again they hit the corner of the 4-deep Pk and "an element or column entering a gap contacts an enemy element or group, the enemy must conform instead". Ergo, the 4-deep then conform to the moving blues (thus ending up with the blues having moved their front edge into contact with the enemy's front edge), and suffer a double-overlap in the ensuing combat.
N.b. however, that the preceding section start's "An element initiates close combat with enemy by moving its front edge into contact with the enemy's: [etc.]" I think that it would probably be open to the blue player to say that he only intends to move his front edge into contact with the enemy's corner, and fight the fight that way instead if he prefers (suppose that for some reason neither player wants the 4-deep Pk to conform). The 4-deep would then fight the fight counting one overlap on its outer corner (which is the outer corner of a column, by the way??
).
Not at all sure about the idea of the 4-deep Pk fighting both 2-deep sets of enemy if so, however, which just "feels wrong"!
