Where the article explains it
Say check A independently has recall against a real defect — the fraction of the time it would catch that class of problem if it ran — and check B has recall .
The passage around this formula
which is smaller than either (1-) or (1-) alone: real, additive protection. But if the two checks share a failure mode — most obviously, if the “second check” is the same model re-reading its own output inside the same context, primed by the same reasoning that produced the mistake — their misses stop being independent, and the joint miss probability climbs back toward : no better than the stronger of the two checks alone, and often worse in practice, because the second pass inherits the first pass’s blind spot along with its confidence.

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
