It is my understanding that the use of iota in the phrase "not one iota of
difference" relates to the epistemological debate about the difference of
the (Greek) terms homoousian and homoiousian.
But yes, Ken suggested iota for the counter and, since all three of us
(Ken, Robert, Rob) had implemented APL interpreters, it seemed a perfect
thing to us, however insignificant iotas may or may not be in gnosiology.
