Stern because the F3 in question was E02+0 not F02+2. (Firestreak, not Redtop - no frontal capability)
The geometry for the crossing leg is 90 x 8 to reflect the turning circle, not the point at which the turn is started. IIRC the northbound leg was flown at about M1.3 with acceleration in the crossing leg and final turn ordered at about 50 off.
IIRC the Concorde intercepts the Lightnings were F020+2, geometry was planned as a 150 x 0 with tgt crossing left to right; ( from dim memory, maybe wrong - acquire and Fox 2 with port Mx in zoom, roll inverted to expose starboard Mx, Fox 2 and pull through.)
However at least one took Judy and converted to a stern intercept.
