Notes in parenthesis are meant to be fretted but not necessarily picked or strummed. It's okay if they ring sympathetically, or if you accidental hit them occasionally. It's also okay if you don't pick it at all. It's a borderline situation!
I think in this case Anders says don't play it, but in the performance play along he actually does hit it occasionally & that's is what the notation is mean to indicate.
This is one of those borderline situations that I wish would have been much clearer since it's the first lesson of a beginner rock course. But don't waste time trying to make it fretted but avoid picking it.
The bottom line here is don't worry too much about it. Play it either way. Eventually you can to play it both ways for more vpossible variety in your skills.
Hope that helps!
