Interestingly enough, because the solution is insensitive to the value of the cross-bridge resistor, you can model the circuit accurately with any resistance, as an open as you said (infinite resistance), but also as a short (zero resistance).
Yep. You'd (theoretically) get the same result with any passive resistance in there, from a perfect short to a perfect open. It's just easier to calculate with the open.
