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
High-throughput virtual screening takes the opposite approach: rather than proposing new compositions, it exhaustively scores a library that already exists. The clearest demonstration is ultra-large library docking, in which researchers computationally docked a library of 170 million make-on-demand compounds, built from 130 well-characterized reactions, against two protein targets: AmpC beta-lactamase and the D4 dopamine receptor [ 8 ] . Against AmpC, 99 million library members were scored, 51 top-ranked compounds were selected and 44 synthesized, yielding an 11% hit rate and, after optimization, a 77-nanomolar inhibitor among the most potent non-covalent AmpC inhibitors then known. Against…

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