Hi , even I believed the same but what I found was when I add HTTPS vip using the same ISE pool members and adding a SNAT , traffic is working fine without any interruption. But when I add a SNAT in the radius vip I am not even getting a reject traffic back from ISE. So what I feel ISE is not even replying back to f5 as f5 is not the default gateway for ISE.
