how can partner have a balanced minimum with 4 hearts, we have shown 0 points. He can't double if he doesn't have them set. This could be based on a balanced hand with good hearts, but it'd certainly be more than minimum.
This may help - poster's definitions:

1♣ = 16+ but if bal its 17+ and if 5♥s its 20+
Dbl = expained as points, penaltish see also our 1♣ definition/
So, it looks by agreement that doubler has either 5 hearts and 20+ HCP or 4 hearts and maybe 19+ HCP.
Either way we should be in game territory so allowing a undoubled partial is quite a deep position and to bid game with no known fit is a guess, hence double and go for the decent plus seems a reasonable course of action.
It may even turn out that either overcaller or lurker may have been pushing the envelope with less that expected shape - perhaps overcalled is 4-5 and the fit is only 8-cards.
On the surface it sounds like partner's shape is either 1534 or 1543 with 20+ HCP but could even turn out to be 2443 or 2434 with 19+.
With no certainty of game, isn't it better to take the almost sure plus of double?
I can't say I like the agreements but that is another thread.
