The jump to 2 ♠ is a fit jump showing at least four diamonds, at least four spades and game forcing values. The method was originally developed in a weak no trump system. In that structure opener always has either extra values or extra distribution. That enabled all weak hands to go through a return to 3-minor. Therefore we could play all other bids as forcing and therefore responder's fit jump could show an invitational or better hand. In the strong no trump system it is less convenient to show all of the minimum hand types for opener and still be able to develop the auction constructively when either partner has additional values. Therefore we make the fit jump to show at least game forcing values.
Opener's 4 ♥ here shows a distributional hand with a spade fit and a shortage in hearts.
Responder signed off in 4 ♠ with a minimum and some wastage in hearts.
Opener has a difficult range for these methods with only a little extra strength. Something like ♠ AQxx ♥ AQx ♦ Jxxxx ♣ x would make slam cold. Although that hand has a lot of good features - two aces and the queen of trump, a singleton and a fifth diamond - and only the ♥ Q wasted so may push past 4 ♠.
