This is allowable by the MPI API. You're specifically telling MPI "I
don't care to know when that send has completed." See the section for
MPI_REQUEST_FREE here:

It's debatable whether that's good programming practice or not
Hello,
I'm looking over some MPI code and saw something that concerned me.
Being a bit new to MPI I don't know if this is a bug or "normal'.
A call to MPI_Isend was made and followed by an MPI_Reqest_free on the
exact same request handle used in the Isend call. I saw the same thing
for ISsend.
