Don't understand that sentence.  Is it about slotting on the same IC package?

If gate swaps were done between repeated identical hierarchic layout sections the result would be like a barrel shift.
The effect would ripple.

The idea would be useful if  swaps were done between repeated identical hierarchic layout sections and nearby glue logic with the
same parts.

I was thinking symbol names as top level of swappable pins, where a symbol is for a schematic section, not
a package.  I think keeping classic slotting as a separate mechanism from pin swapping would be best for usability
and understanding, (especially since few will be interested in classic slotting with dual and quad packages -- they'll just use 
programmable glue logic chips, where the number of pins involved is better called pin swapping).
