Geometric Differences in FDR Control

In a series of conclusions, the author points out that their constructed example defies the common intuition that "negative correlation breaks FDR control." Instead, it is a positively correlated construction; it satisfies the PRDN proposed by @weijie444 but fails to meet the standard PRDS.

The author uses this to demonstrate that the geometric structures of one-sided and two-sided tests differ vastly, meaning they cannot be understood through the same intuitive lens.
