The way these two opcodes are combined by the compiler to implement except* is described in the pseudo code here: https://github.com/python/cpython/pull/29581#issuecomment-975660029 except* uses JUMP_IF_NOT_EG_MATCH. The excepts (not-) that collect exceptions raised in the except clauses are virtual. The do_reraise_star at the end is PREP_RERAISE_STAR followed by POP_EXCEPT_AND_RERAISE.
