I keep in touch with several HS coaches, from small schools through 5A with our largest being 6A in KS. These guys are coaching anywhere from the veer to the spread. All are teaching their QB's to read someone, tackle, DE., safety, it doesn't matter the O. They will also say that how much you give the QB to read depends on them and their ability to pick it up. One went from an assistant in HS to head JH and they generally do not teach the QB to read, just run the designated play. Reading takes time.
My point is what's the difference?
Here is one article that explains the veer concept

Here is a short one with some clips that shows how the QB is reading the play side designated person, may be a DE bit still a read.

I use Brook as an example because I knew him in HS and he definitely did not play option FB in HS. On the other hand, not all HS QB's you see are necessarily making reads, they are running designated plays a lot of the time.
