@@ -315,6 +315,13 @@ Pack/Unpack has quirky interactions on [[sv/mv.swizzle]] because it can
 set a different subvector length for destination, and has a slightly
 different pseudocode algorithm for Vertical-First Mode.
 
+Ordering is as follows:
+
+* SVSHAPE srcstep, dststep, ssubstep and dsubstep are advanced sequentially
+  depending on PACK/UNPACK.
+* srcstep and dststep are pushed through REMAP to compute actual Element offsets.
+* Swizzle is independently applied to ssubstep and dsubstep
+
 Pack/Unpack is enabled (set up) through [[sv/svstep]].
