PLEASE HELP with QSYGETPH QWTSETP QSYRLSPH

I have done this before, but I seem to be missing something
and cannot figure out the problem
I am hoping someone will spot what I am overlooking
I am running V5R1M0
*PUBLIC has *USE authority to QSYGETPH QWTSETP QSYRLSPH
USR01 has *USE Authority to Profile USR02
USR02 has *USE authority to Profile USR01

I have a test program where I am doing the following:
Signed on as USR01
Get a profile handle for USR01
Get a profile handle for USR02
Switch to profile handle for USR02
Test User Profile by attempting to Display a file
Release profile handle for USR01
Release profile handle for USR02
Test User Profile by attempting to display a file

This 2nd test fails because I am still running under USR02
When this program finishes, the job us still running under
profile USR02
It does not return me back to USR01

Both WRKF command execute so I know there are no errors in
the CL
I run through debug and the ERRORCD returned with each call
was blank
The first attempt to display the file fails so I know it has
switched me to profile USR02

Here is the code
