The article mixes two things: (1) That you should (depending on requirements) have one system of records while the other systems are merely systems of reference, and (2) that in that architecture, when (*) you write to both systems or read from both systems for the same logical record, then in the writing case you have to write to the system of records last, and in the reading case you have to read from the system of records first. The article however doesn’t make it clear that the titular rule is specifically (2), and that it is conditioned on (1) and on (*).

I have no suggestion for a better name off the top of my head. The issue I see is that you already have to know well its context and when it applies, also in order to not misremember it as “Write First, Read Last”, and to not mistake it as LIFO, or to relate it to a read-modify-write scenario in which you naturally would read first and write last anyway, though in a different sense. You see how the name is confusing?
