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
where and are a chosen behavioural metric measured on the clean and corrupted runs, and is that same metric after the activations of component set are copied from one run into the other. A score near one means patching alone restores nearly all of the clean behaviour; a score near zero means it restores almost none.
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.
