Finally someone else pointed this out. I think when Kirsch compared the two plots from OWID, he accidentally compared the March 2022 spike for cases against the October 2021 spike for deaths. There's a pattern of 4 roughly equally spaced spikes, but the first spike for cases was so low that it's easy to miss (especially with OWID's irregularly spaced x-axis labels).
