Aviation speeds are named by their operational purpose. In computing, if I share a password between site A and site B, when I login to site B, I'm still logging in using my site B password.
Start at 5m20s where the definitions are given. V1 is the decision speed. Vr is rotation speed. V2 is climbout speed.
What this crew did was compute based on a given headwind to find a V1, Vr, and V2 and then chose an operational Vr that was the same numeric value as the computed V2. That doesn’t make the speed at which you rotate no longer the Vr, but rather the value of Vr be the value of the previously computed V2.
This is laid out at 6m34s where the presenter says they picked the Vr to be the value of the computed V2.
