That's 90 minutes in the air, not total trip time.
The HSR is 160 minutes from downtown to downtown. There's no check-in, no security check, no arriving 1-2 hours early, no travel to and from the airport. When you count all of that, HSR will be faster than flying. It's also far, far more comfortable - there's no comparison there.
