About a decade ago, Mark Zelden and Paul Beesley shared with me:

On z/OS 2.2 I just used it to start two SMP/E on different CSI. A rudimentary
test succeeded. It does no ALLOCATE nor LIBDEF nor ALTLIB.
I had wondered how SMP/E avoids DDNAME conflicts on SMPCSI. A TSO LISTALC
shows that **.GLOBAL.CSI are allocated to two different generated DDNAMEs.
