Personally I used to start with "the last system" - that means HSA
update, and then ACTIVATE SOFT on rest, however the "more recommended"
way is the above.
Did this actually work this way? Seems to me that the hardware & software
activate on the first lpar would make the rest of the systems think they are out of
sync and would refuse to even do a software only activate? Its been a while since
I tried it

Yes, it does. I'm pretty sure about it, I did it many times. A lot of.
BTW: just try this.
My humble opinion: people tend to think IODF ACTIVATE is dangerous. It
isn't. In most cases the ACTIVATE will not work due to some reasons.
Adding devices is safe. Removing or altering devices require the devices
(or channels) to be offline. Offlined device is not used by any
application (with exception to FDR and similar). IMHO the most important
risk is to have a system out of sync with HSA, which can be fixed
dynamically when the system was in sync. For fresh-IPLed system the
solution is to re-IPL.
Disclaimers (fine print):
I did not considered parallel sysplex things like CF and sysplex links
