That doesn't sound like a conflict to me. People actively resist allowing vomit to touch most of their mouth. We tend to do the opposite with soda. So swishing with water after vomiting puts vomit where it otherwise wouldn't have been, while swishing with water after drinking soda only dilutes the places that soda already was.

The brushing thing has to do with the effect acid has on enamel.

I doubt you could find a dentist that wouldn't recommend swishing with water after drinking soda.

Perhaps I am an explosive vomit-er, but mid-act, I have little concern to what area of my mouth is being exposed. I would consider my entire mouth to be vomit coated. Whereas soda would be mostly concentrated to the bottom fraction of my mouth, predominantly on my tongue.

Acidic vomit or acidic soda seem like roughly the same thing. Either it should be diluted and swished or not.
