 That is correct.  Once a job has done an ETCRE for an entry table 
which contains at least one space switch entry, LXRES, AXRES, and 
ETCRE will result in a 052 abend in subsequent job steps.

  Entry tables do not persists across job step termination,
regardless of whether the entries are SS of non-SS.
