Those tickets do not allow you to cross states. The Hessen ticket is valid for travel within Hessen only.
For such a trip, a 49 EUR tickets may or may not be worth it, you need to make the maths. It is valid accross Germany for all public transports and train (except ICE/IC/EC trains). It is a subscription, but you can cancel it anytime.
