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
Weighted least squares achieves zero residual on any data that lie exactly in the range of B . If y truly equals B for some vector — meaning a genuine, single-valued scalar potential sits at every node, however violently curved the spacetime that produced it — then itself drives the weighted sum of squares to exactly zero, which is the smallest value the nonnegative objective can take, so the fitted values equal y exactly and r 0 . This holds independent of how strongly varies from node to node, independent of C , and independent of the graph’s shape, because it is a fact about linear regression, not about gravity: any closed loop of…

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