Teaching for a clarinetist

Today, I've checked some books of my sister (in Spanish). According to my main interest I caught a music book. There was a picture in which you could see a girl playing a clarinet:

I, as a good clarinetist since several years ago, have been able to see something WRONG!
 Look at the girl's mouth! Look the position of the clarinet in her mouth! Now, see a correct picture:

Is my sister going to learn this??? 

Explanation:
If you aren't a clarinetist or unless you know what I'm saying, look at the mouth of the two girls and you'll see that this part of the clarinet is back to front.

Like good teachers used to tell: Music is not learned from books.
