What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
The arithmetic also misbehaves exactly where the events are most interesting. As the counterfactual probability falls toward zero, . AR6 records that several studies of events from 2016 onward reported an infinite risk ratio, corresponding to a fraction of attributable risk of one, because the event’s occurrence probability was close to zero in simulations without anthropogenic influence — while noting in the same passage that the lower bound of the uncertainty range is difficult to estimate accurately in these cases [ 1 ] . Paciorek, Stone and Wehner develop a frequentist framework for exactly this sampling problem and argue that the bootstrap widely used in the…
