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 , the number of pixels crossing threshold at a given instant, is normally far smaller than the total pixel count for a mostly-static scene. That scene-dependence is also the sensor’s clearest limitation rather than a free efficiency gain: because each pixel’s operating principle is defined by Gallego and colleagues as asynchronously measuring per-pixel brightness change and encoding “the time, location and sign” of that change [ 3 ] , a highly textured, fast-moving, or vibrating scene drives toward , and the bandwidth and power advantage over a frame sensor narrows or disappears for exactly the scenes…

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