'A' won't work, because particles from both '1' and '2' will try to bind with '2', so you'll get cross-binding happening.
'B' will work fine, just add all particles to some 3rd group. Groups are just bitflags, so you can put particles in multiple groups at once.
So add top particles to group '1' and '3' and have bind with '1'. Add bottom particles to group '2' and '3' and have bind with '2'. All particles will still collide because they're all members of group '3'.
