The Laue condition fixes the component along the beam; a half turn about the spindle negates the two perpendicular to it and taking -h negates all three, so the composition leaves the beam component alone and the mate is on the sphere exactly, not nearly. Says that they are separated by half a turn rather than recorded together precisely because the Ewald sphere is curved - a near-flat one would excite both at once - and that the positions need only the reciprocal lattice to be centrosymmetric, Friedel's law entering as the test of a pairing rather than its basis. Also states the yield: a sweep of S degrees gives S-180 degrees' worth of pairs, so half a turn gives none and a little over half a turn gives few.
