i think the original have 5-10 point and the bid was 2♦
4+♥and 4+♠ the SPREAD version is even more weak
4+ ♥ and 4+ ♠ 0-7(8) HCP 8 is for balanced hand
with more point you open 1♣
bad example
south open with 2♥
west pass
north don't like ♥ and corect to 2♠
East pass
east lead A of ♦ and K of ♦ and give his partner a ♦ ruff
West ruff and cash the Ace of♥
2 ♠ +1 made
