I don’t really like the block-universe thing in this context. Here “reversible” refers to a time-course that doesn’t particularly have to be physical causality; it’s whatever course of sequential determination is relevant. E.g., don’t cut yourself off from acausal trades.
I think “reversible” definitely needs more explication, but until proven otherwise I think it should be taken on faith that the obvious intuition has something behind it.
