Without more context I don't find this note clear and explicit. It
could just as well be distinguishing the case of standalone degree
sign from that where the degree sign is followed by something else
(like C), as distinguishing degrees of temperature from those of
alcohol or arc.
As it happens, after reading much of this discussion yesterday, I
went home and noticed the bilingual labels on a container of
medication. There is a warning about not storing it at a temperature
(on the English side): "30°C"
(on the French side): "30 °C" .
Of course °C is non-SI anyway, so we have nothing to worry about...
