As mentioned in the article, story-pointing is not about finding the perfect score for each task.
From my experience, it was always about uncovering potential problems or, contrary, easy solutions, that people think everyone understands, up to the moment when one person estimates "3", and the second one "8". The discussion at that moment is the most valuable part of the estimation, not the final story points value.
