The distance that these rods enforce is from the beginning of one column to the next. So, if we have two notes, there is a distance set between two PCs. For ties at the beginning of the line, the rod governs a NMPC on the left and the PC on the right that is associated with the NoteHead. In the latter case, minimum-distance specifies a rod of that length between the beginning of the line and the PC; the tie is drawn within whatever space is available to it.
