Section "2.3.4 Errors and Optimization" of XP31 explains this. If the variable
is never called, it need not be evaluated. In such cases it is implementation
dependent whether the dynamic error is raised (i.e., with eager variable
evaluation, the error may always be raised, with lazy evaluation only when
actually evaluated).
