Mostly just a dull safety step. You know what it was used for but some unsuspecting person may come along and use it (maybe you were hit by a meteor) for some other chemical that may react with the leftover herbicide residue.
But, practically, different herbicides can be used to selectively target specific weeds. You don’t want to be trying to treat dicots but still have some monocot-affecting herbicide or, even worse, glyphosate left over in the tank/pump.
Makes sense. I really only spray in the fenced yard and because we have dogs that have free access and we live in a protected area along the Mississippi River I make my own that’s pet and wildlife safe.
It’s a gallon of vinegar, cup of salt and a tablespoon of dish detergent.
I pretty much only use dish detergent and, separately, a copper fungicide. Florida humidity and rain combines to create some mean fungal infections and I’m near a sinkhole/spring so I, too, have to be careful of runoff.

That’s a good combo to use frequently.
