The passage around this formula
…Reading out a result, however, generally requires erasing or resetting some register, and that step is bound by a different and independent piece of physics, Landauer’s principle: erasing one bit at local temperature T costs at least T2 of dissipated heat [ 6 ] , made precise with finite-size corrections by Reeb and Wolf [ 7 ] . This bound does not care about horizons at all except through whatever value T takes locally — which, per the cooling analysis above, only becomes horizon-dominated at the…

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.
