What's the mass of your rigidbody, and the mass of each rope particle?
Attaching two points allows you to remove degrees of freedom (DOFs): attaching just one particle results in a ball/socket type attachment with 3 rotational DOFs. This allows the chain to rotate around the attachment point, which is not desired in this case.
By attaching two particles you remove 2 out of the 3 rotational DOFs, and the rope sticks out straight.
