This is how we work since the beginning of ATC in the 1920s.
what you are missing is this

If the crew planned an intersection and they're trying to takeoff with half the runway missing, it's very different from a situation in which they plan the takeoff from the beginning on the shorter portion.
Also, we don't really have the proper timeframe in the recording, but it's likely the captain said they could takeoff from there very quickly. Whereas you need quite a long time to do a proper performance calculations...
so it's one thing requesting intersection at the gate and completely another having the plane configured for takeoff with 2300m runway left and then entering the runway at the wrong place so you have only 1300m left, I'm not familiar how much time it does take to reconfigure the T/O configuration on Embraer and recalculating everything but I am willing to bet it's not significantly less than just taxiing to D6
