Since pdb is a linear format (one residue follows another), it will
be impossible to have 3 residues immediately following an initial one.

Assuming r1 is bonded to r2,r3,r4:

E.g. if your residue order in the pdb is r1, r2, r3, r4, r1-r2 are
bonded so no TER between them. But r3 is not bonded to r2, so there
needs to be a TER between them. And so on.
