I think they are conflating "serif" with "Times" Times is a very narrow font, which has all sorts of readability issues (it's very readable for the space it takes up, but damn it's narrow). I have yet to see an OCR do better on a serif font that has a bit more girth to it. In particular I see things like "III" as being impossible to read for both OCRs, and (in the absence of context) humans in sans-serif fonts.

I'd put up a nice sans typeface with single-storey "g" (the double-storey "g" is hard to read for a lot more people than one might think) against a sans-serif any day.
