What was in the high half of the registers when it was in 64 bit mode?

Can anyone explain why the following code did not work in AMODE 64 but works in
AMODE 31?
I received an ABEND S602 R15=0 on the POST.
Abend: S602
Explanation: An error occurred during processing of a
POST macro instruction. The system issues this abend
only in association with cross memory post processing.
The hexadecimal return code in register 15 indicates the
nature of the error:
Code Explanation
00 The target address space control block (ASCB)
is incorrect.
Per the manual STIMER, WAIT, and POST support AMODE 64.
STIMER REAL,STIMERX,DINTVL=WKWAITI
XC STIMECB,STIMECB
OI WAITLAST,X'80'
WAIT 1,ECBLIST=WAITLIST
STIMERX DS 0H
* TIMER EXPIRED
DROP R12
USING *,R15
*C POST STIMECB In AMODE 31
POST STIMECB,X'40' <== Abends on an S602 reason code 0
DROP R15
*C RETURN
BR R14
WAITLIST DS 0F
ASMNSTOP DS A
WAITLAST DC A(STIMECB)
STIMECB DS F
When I added the following before the STIMER it worked:
SAM31
SYSSTATE AMODE64=NO
