I understand your point and there are several competing comparisons here. Generally only collection functions take the coll first. eduction is similar to sequence (and into and reduce and transduce) in taking it last (but differs in taking multiple xforms). The multiple xforms are similar to ->> though which works left to right and puts the source first. I think I'd rather emphasize it's similarity to sequence than its similarity to ->>.
