The single nucleotide in this case was not shown to cause the phenotype; it was just a marker (SNP). The likely cause is variation in the promoter.
IOW, it still counts as evidence against Schindewolf's claim of correlation between the magnitude of events at the DNA and phenotypic levels, it just doesn't fit into the category of single-nucleotide substitutions.
