Doesn't -chainsep take an argument?

It is stated:
The separation of chains is not entirely trivial since the markup in
user-generated PDB files frequently varies and sometimes it is desirable to
merge entries across a TER record, for instance if you want a disulfide
bridge or *distance restraints* between two protein chains or if you have a
HEME group bound to a protein. In such cases multiple chains should be
contained in a single molecule_type definition. To handle this, pdb2gmx has
an option -chainsep so you can choose whether a new chain should start when
we find a TER record, when the chain id changes, combinations of either or
both of these or fully interactively.
And if I use:
In my topology:
; Include chain topologies
[ molecules ]
; Compound #mols
So how can I have one [moleculetype] for the usage of distance restraints?
Why do they state that this option will allow to have one [moleculetype] ?
