Yep, that's right. Not relevant, we can say.

When V1 and VR are the same, runway lenght is not limiting ("infinite") for the stop case. And we are using the maximum possible V1, which is the best for the Go case (shorter take off distance). So performance is very good, runwaywise. But you can still have marginal performace for climb and obstacle clearance, though.
refer to my other post, if you like
regarding the rejecting take off after VR... Never an option. In the infinite runway it would be a quick take off and landing. Once you rotate, you never ever reject take off.
