The passage around this formula
Now define . subject to 1-> and to a fixed rule for which fragment partitions are admissible. The displayed g records the physical parameter of interest; under the Haar-average convention the resulting scalar is independent of its coordinate label. A worst-case definition would retain explicit dependence until the infimum is taken.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
