Are you using "intercity" literally, as in "between cities"? Intercity (IC) is a specific type of train in Germany, which (aside from some edge cases) you can't use with the 49€ ticket. I think you're thinking of the REs (RE is short for Regionalexpress), those go between cities too, but make more stops in smaller towns etc, and those are included in the ticket.
