That's true.

Lets take a look at 4000/4002-2.sym. Load it three times and attach 
slot=1 and slot=2 to two of the symbols.

All three symbols have now different pinnumbering. Those with slot 
attributes are wrong.

The solution is ordering the slotdef definitions:
slotdef=1:2,3,4,5,1
slotdef=2:12,11,10,9,13
instead of:
slotdef=1:1,2,3,4,5
slotdef=2:13,12,11,10,9

The pinseq attribute will not change.
