My first thought was your first option, which is why I specifically
responded with explanation about how data type selection can viably be
about expectations rather than certainties, but he responded with a
one-word "Wrong" so I must have been answering the wrong question.
I've no idea about the misreading of "multiplier". A fourth
possibility is that mathematics works differently for him and for us,
which I suppose is possible; when I visited sci.math a while ago, I
found some people for whom everything I'd learned in grade school was
clearly wrong, and they were doing their best to enlighten the world
about the new truths of mathematics that they'd found.
