Even though I doubt an LPAR would go down suddenly... Really, the only time the profiles are read is when the LPAR is shutdown (shutdown -F) and then restarted from the profile. Reboots (shutdown -Fr) do not re-read the HMC profiles. So in your scenario where your LPAR "goes down suddenly", which profile is read would depend on how the LPAR is started back up. If it reboots on its own, then neither profile is re-read. It stays in the same state that it was when it was originally booted. If you manually start it, then you will be choosing which profile is used.

NAME
profiles - print execution profiles for a user
SYNOPSIS
profiles [-l] [ user ...]
The profiles command prints on standard output the names of the execution profiles that have been assigned to you or to the optionally-
specified user or role name. Profiles are a bundling mechanism used to enumerate the commands and authorizations needed to perform a spe-
cific function. Along with each listed executable are the process attributes, such as the effective user and group IDs, with which the
process runs when started by a privileged command interpreter. The profile shells are pfcsh, pfksh, and pfexec. See the pfexec(1) man page.
Profiles can contain other profiles defined in prof_attr(4).
Multiple profiles can be combined to construct the appropriate access control. When profiles are assigned, the authorizations are added to
the existing set. If the same command appears in multiple profiles, the first occurrence, as determined by the ordering of the profiles, is
used for process-attribute settings. For convenience, a wild card can be specified to match all commands.
When profiles are interpreted, the profile list is loaded from user_attr(4). If any default profile is defined in /etc/security/policy.conf
(see policy.conf(4)), the list of default profiles are added to the list loaded from user_attr(4). Matching entries in prof_attr(4) provide
the authorizations list, and matching entries in exec_attr(4) provide the commands list.
The following options are supported:
-l Lists the commands in each profile followed by the special process attributes such as user and group IDs.
Example 1: Sample Output
The output of the profiles command has the following form:
example% profiles tester01 tester02
tester01 : Audit Management, All Commands
tester02 : Device Management, All Commands
example%
Example 2: Using the list Option
example% profiles -l tester01 tester02
tester01 :
Audit Management:
/usr/sbin/audit euid=root
/usr/sbin/auditconfig euid=root egid=sys
All Commands:
*
tester02 :
Device Management:
/usr/bin/allocate: euid=root
/usr/bin/deallocate: euid=root
