A reply from my co worker:
: My question is only according to the shita that you do not repeat s.e.
: on Motzaei Rosh Chodesh because you are not marviach yaaleh veyavo
: Clearly if you hold that missing a hazkarah makes the s.e. as klo
: hispalel "kepshuto"  then of course you would repeat s.e. on motzaei
: rosh chodesh. 

: But even if you say that repeating s.e. is in order to be mashlim the
: hazkara it could still be that as long as you did not say "all" required
: hazkaras in one s.e.  it is not called davenen s.e. ktikuno and you
