Where the article explains it
Under balanced arms and otherwise ideal readout, V is the remaining fringe visibility.
The passage around this formula
Under balanced arms and otherwise ideal readout, V is the remaining fringe visibility. That statement belongs to ordinary complementarity, not black-hole mysticism. Englert derived a quantitative visibility–which-way bound for a two-path interferometer, and atom-interferometer experiments later measured visibility and distinguishability independently in agreement with the relation [ 11 , 12 ] .

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.
