I think backing the rockers off on the unaffected side is more than you needed to do. The reason most of us, doing a full top end, just do #1, and then #4 (and could do it the other way around, but we don't), is that it is a bit easier to set things up having less rather than more spring pressure to deal with when moving the cam. On the other hand, having other springs at work kind of counter balances the pressure of the valve you are working with, so it probably is a wash. Another reason to do just the first two is if you run into issues you have less wasted work if you decide to disassemble and recheck.

It is reasonable to expect that nothing changed on the unaffected side - how could it? However, you could check #4 (after resetting the lash) as a way of understanding where it is, so you can match #1 to it.
