just observing that there are different words describing the same things

no, not at all correct and you do need to ground your comments in reality
Pass does not equal row, pass refers to the # of circuits (passes) the fluid makes across the face of the rad

i.e. the original BI was a 1 row (single core) 4 pass rad (4 in series, unequal air)
the next BI was 1 row 2 pass (2 in series, mirror air w/unequal flow)
the BIX is a 2 row 2 pass (two 2 row in series)
and now they have both 1 and 2 row in both 1 and 2 pass configurations

over here, in the automotive world they use 'core' for row (of tubes) which may be in-line or offset
the rows may be in series or parallel, or divided into segments; all of which present different 'cross-flow' configurations wrt the air side
I have tested tube flow configurations not commercially offered (translate: followed theory out the window) with no discernable effect

feel free to opine, I did suggest to use our terminology - which means to understand it, no ?
