You are right if seasonally adjusted numbers are used.

However, the values are not seasonally adjusted because seasonal adjustments don't really apply (or shouldn't) to YOY numbers, the focus of the chart.

The main idea is the YOY numbers are well out of date by the time they're published and may not reliable indicators of the current state of prices.
