I agree with you, except that the hello-time is 2 seconds by default, so in RSTP the max-age is actually 6 seconds by default (3 missed hello BPDUs). That was one of the major changes they made with RSTP for faster convergence time...instead of waiting 10 hellos they changed it to 3. I remember thinking the exact same thing when I was a student going through these.
