Yes, that is how it works. There is no communication between the 
collision part of ODE and the solver part of ODE, except for the contact 
structure (which is an output of collision, and input of contact joint

No. The ODE solver solves all constraints at the same time. That's one 
reason why robust contact filtering (merging near-coincident contacts) 
is a good idea.
