I got a really similar problem with the same PowerHA version. The only difference is the AIX version I have, which is: 7200-05-08-2420.
Even in my environment, after the failure of node A, and RG failover on node B, I got the "network recovery message", but running the cluster verification, cluster says:
" Network: net_ether_01 State: DOWN".
So, even if cluster state is "ST_STABLE" on node "A",trying to switch back the RG using cspoc feature, PowerHA doesn't show the node "A".
I didn't test with a different PowerHA version, but you did it. So I believe you are right, there is a problem with this PowerHA version.

PowerHA 7.2.8 Network Down Failover Problem
*Build environment #1 (Result: Abnormal operation)
AIX 7.3 TL02
PowerHA 7.2.8.2
STARTUP="OHN"
FALLOVER="FNPN"
FALLBACK="NFB"
# PowerHA Test Scenario
1. Node A's network down: Failover to Node B (normal)
2. Node A's network recovery: Node A network recovery message (normal), Node B RG online
3. Node B's network down: No response after Node B network down message
4. Halt of Node B (in the above state): Failover to Node A (normal)
*Build environment #2 (Result: normal operation)
AIX 7.3 TL02
PowerHA 7.2.7.0
STARTUP="OHN"
FALLOVER="FNPN"
FALLBACK="NFB"
1. Node A's network down: Failover to Node B (normal)
2. Node A's network recovery: Node A network recovery message (normal), Node B RG online
3. Node B's network goes down: Node B network goes down and then fails over to Node A (normal)
Just in case, the same thing happens if you change the Fallback Policy to Fallback To Higher Priority Node In The List.
In 7.2.7, it works normally in case of network failure.
However, in 7.2.8, it operates abnormally in case of network failure.
I suspect it is a bug in 7.2.8.
Has anyone experienced a similar case?
