Do you think this is somehow a point in their defense? Corrections for multiple comparisons reduce the significance numbers of your results; probably they found that if they corrected for multiple comparisons their p-value was above 0.05 and they wouldn't be able to publish their paper, so they undid it. (Alternatively, they were lazy, so they skipped it).
