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
is the actual multimodal increment — what the removed channel contributed beyond what text alone already bought. A large with a small is not evidence of multimodal competence; it is evidence that the benchmark, not the model, is doing something unimodal. Reporting alongside costs one extra evaluation run and turns an unfalsifiable headline number into a checkable one.
