How has section 654 of the California Criminal Code been interpreted in the context of an individual forgery and an individual attempt to extortion?

With respect to the individual attempted extortion offenses, each offense was not a means to accomplish either of the other two offenses, but rather a distinct and separate effort to persuade Merida through force or fear to part with his money. (See People v. Neder (1971) 16 Cal.App.3d 846, 854-855 [separate punishments for three forgeries involving a stolen credit card used in three departments of one store in a single day did not violate section 654].)
