The sequence of mutations leading to Omicron is a one-off. Presumably, if there were a thousand variants with the same N mutations as Omicron, you'd see ratios like the ones you describe, but there's only one Omicron. The previous poster is pointing out it's plausible (~5% chance) that the path Omicron took has only 4 S mutations.
