Absolutely correct - having conducted anti-icing certification trials myself this was a prime consideration. The pilot must generally have a clear view of the 'controlling' area for holdover, and this area must be de- or anti- iced first as that is when the holdover clock starts. Inner wing root on the pilot's side is the preferred spot for the first application of anti-icing fluid when a two-stage decontamination is performed. Nothing aerodynamic here, just a practical operational consideration.
