That seems to make sense to me: tighter lash = valves open sooner = lower cylinder pressure. Like a "bigger" cam with more duration will give you lower cranking pressure with the same static compression ratio & a smaller cam. Wider lash = valves stay closed longer = higher cylinder pressure?
I'm surprised the pressure change a small amount of lash change made, though.
