stopping note with middle finger, per Delcamp 03

[DonnaSutliff]

On page 4 of delcamp 03, it is indicated that one should stop sounding the B (second string) with the second finger, at the same time producing an A, (first position), on the third (G) string, with the second finger. Is this a typo? How can this be done? I admit that I have not developed note-stopping as I should have despite the years of playing, and the notation indicating note-stopping is new to me. Perhaps I am missing something.

It isn't a typo. The way M. Delcamp does it is to lean the finger over in such a way that it damps the higher string while fretting the new note on the adjacent string. He mentions it a few times in the lessons, perhaps the clearest being here, where he demonstrates it in the fifth video down. That one relates to exercise 41 in level D02 (page 84), and involves the same notes as in your question.

This is a very common technique in classical guitar if you're talking about the left hand, which I assume you are. The pad of your left finger stops the open string whilst simultaneously fingering the note on the adjacent string. The finger has to lean a little bit to stop the open string.
