You're definitely right that it could have been better: I now realize that I made a poor assumption. Re-quoting:

> IEEE infinities
From context, I took this to mean that the mathematician in question objected to IEEE infinities _because +/-inf "aren't numbers"_, when her opinion could easily have been something rather more nuanced like "the utility of floating-point arithmetic is reduced by the inclusion of values that are not real numbers". There are legitimate issues with IEEE arithmetic, like the fact that infinities are produced despite the general rule that results are supposed to be rounded to the nearest representable value (which can't ever be infinity).
My apologies for presuming to know the reasoning of someone not even party to the conversation!
