In fact, the 30-year-old looked as dumbstruck as everyone else that evening in the Edmonton Commonwealth Stadium.
But Pintusevich-Block will get the chance to prove last year was no fluke when they meet face-to-face in next Friday's Norwich Union Grand Prix at Crystal Palace.
And the Ukrainian is warning that her restful summer has made her even more dangerous than last year.
She told Standard Sport: "I decided to take a break this season. Major championships take a lot out of you mentally and physically.
"I'm 30 now and I have not had a break in 11 years, so as there was no World Championships or Olympics I planned to take a rest this year. You have got to look at the bigger picture and that's the World Championships next year and the Olympics in Athens in 2004.
"But I actually feel like I am in better shape this year.
"I didn't run under 10.9secs throughout all of last year, but this year I have done it twice, so I'm ready for Crystal Palace and Marion Jones and really looking forward to it."
Despite finally gaining revenge for the World Championships in Athens in 1997 when Pintusevich-Block celebrated victory in the 100m only to be told that she had lost to Jones on a photo finish, Pintusevich-Block says last year's triumph has not changed her life.
She is still relatively unknown in the Ukraine where footballers such as Tottenham's Sergei Rebrov and Andriy Shevchenko of AC Milan are still king.
She said: "It didn't change anything for me because I had already had some success before. And besides track and field is not the most popular sport in the Ukraine.
"But for me it was definitely the best victory of my career, the most significant. It was always my dream to win the 100m dash.
"I also took revenge for 1997, I made a mistake that day, I thought I had won and I hadn't.
"I had been waiting four years for the opportunity to set the record straight. Now it is done I don't have to worry about that any more. I am world champion, everyone is now looking at me and I am happy about that because I proved myself.
"Yes, maybe now I feel a little bit more responsibility because everyone is looking at me.
"But last year wasn't a fluke. I have the fastest time in the world this year, so people know last year was not an accident and that I didn't just get lucky one time.
"What I have to remember is that no athlete should ever see another athlete as unbeatable.
"That's what last year taught me. I am beatable and so is everyone."
