Yes, the terminals on the speakers and the terminals on the receiver are just terminals. Everything connected to them, is completely connected to each other.
In the receiver, on it's circuit board is the actual amp. There is a wire, or a trace on the board (electrically the same as a wire) which connects the amp to the connector.
In the speaker, there is a wire from each of the connectors (typically jumpered to make them electrically one), or a trace on a board (again the same as a wire), to the HPF and LPF parts of the crossover.
At least some of you are beginning to grasp the concept that the current in the speaker cables will be different even though the crossover is upstream. You don't need the crossover downstream to create the difference. That was the error most people were making when arguing against bi-wiring.
Again, I am willing to accept this from you.
But this difference in current would have always existed on the two wires from the speakers connector to the two parts of the crossover.
All bi-wiring does is change the point in the circuit where it goes from one wire to two. It does not in anyway electrically change the circuit, merely the amount of wire to achieve exactly the same thing.
Possible advantages? The reverse current created by the driver's coil moving inside a magnetic field can be better damped by the amp rather than being more free to cross effect the other driver.
If an amp was better able to dampen such reflections, the amp would need to have two outputs for each channel, with separate paths to separate connectors for bi-wiring to take advantage of this capability. Whether the point of electrical connection is at the speaker terminals or the amp terminals is irrelevant to anything travelling on the wires - they are all connected without any magic dampening capabilities being applied.
