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
read as: for every input within radius of , the system’s output stays inside the safe region. That “for every” is doing all the work, and it is exactly what no classifier bypass rate and no red-team hour count can claim — those are statements about a sample of inputs that were tried, not about the full set that could be.
Learn the underlying idea
A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
