I just received a PM from @hius07 that the current PW4 JB method doesn't appear to be working on the latest FW 5.13.4 OTA update. There's only been one case thus far and we haven't tested it ourselves.
To be safe though, if you wish to be able to jailbreak your PW4 make sure to enable airplane mode so it doesn't automatically update to 5.13.4.
