I presume you mean into the flank? We explored that but what I didn't show was another Wb element preventing the Psiloi from making a legal corner to corner contact on the flank. The owner of the Psiloi chose not to slide to conform given the blocking Wb element (who would have slid sideways to make room) would have ended up overlapping the already disheartened Psiloi (side edge to side edge, it was a bit of a mess) giving a net factor of zero. So once that choice was made to not conform (I presume sliding is optional if you don't have to conform?) then the Psiloi is simply TZ'ing the Warband unless there is some other provision for making a legal contact at that point in time without spending PIPs? Personally I can't see any other way than what you described, and what was discussed at the time, but my opponent declined to make the Psiloi conform.
