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 the teacher’s and student’s output logits, a softmax, T a temperature that softens the distribution, and y the ground-truth label. The second term is the entire point of the method: it transfers the relative probability the teacher assigns to every wrong answer, not just which answer was right, a far richer training signal per example than a raw label alone provides. That is the rationale, stated plainly by the paper that introduced it.
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.
