1) The latest or the greatest?
Notwithstanding what it says about &SYSM_HSEV in
HLASM General Information R5 (GC26-4943-04),
Appendix B. System Variable Symbols, it seems reasonable
to assume that it contains the greatest MNOTE severity
so far in the assembly.
2) It's not clear exactly when PUNCHed data is written to
SYSPUNCH and/or SYSLIN. If they are buffered and
written out only when complete, then abandoning the
assembly (if that's possible) will prevent erroneous or
incomplete JCL being submitted. If they are written
out at the time the PUNCH statement is encountered,
they may be irretrievable, especially if SYSOUT still
emulates unit record devices as it always used to.
3) You obviously have more experience with pornography
than I.

Because it's a good idea to check the assembly completion code to
ensure that the generated JCL is good. That way you can avoid submitting
partially and/or incorrectly built jobs to the internal reader.
The original suggestion that a two-step scheme be used seemed to me to
share a salient characteristic with certain kinds of pornography: One
looks at them and thinks to oneself, "I see that it can be done that way,
but why?"
The assembler's 'completion code' can be checked WITHIN a single assembly
step using the value of the HLASM system variable symbol &SYSM_HSEV, as in
|&abort setb (&SYSM_HBSEV ge &abort_severity_level)
| aif &abort).abort
in which &abort_severity_level, initialized in a SETA statement, has any
desired value, for concreteness say 4.
