It's too bad they did all of this setup and just did one accelerating run, starting from way up at 2000 rpm at the motor

IIRC it was the limits of that dyno both on the bottom and top end. He ran into the same caution when he was testing his Tesla-powered Evora.

Short.

Sasha owns the dyno (https://www.onpointdyno.com/about/ <-- Mobile Dyno service), so, he probably knows it well and doesn't want to wreck it
