Saboteur 2 - result problem

[ilfabbra]

Hi,
I have played a match to Saboteur (sab 2) but I didn't understand the result. We were in 4 people: 2 blu team, 1 green team, 1 geo. We finished the path to gold with no door and the last player to find the gold was the green one. Why did he win 5 gold and the blue team 0 gold? I thought also the blue team should obtain the gold.
The image may help to explain me.

Thank you for the help!!

Blue and Green Gold-Diggers (4 each)
Both teams try to tunnel their way towards the treasure, but they are in competition.
A team wins if:
● a dwarf from that team creates the connection to the treasure and the way there
isn‘t blocked by a door of the other color

Both teams win (along with all other “non-Saboteurs”) if The Boss, The Geologist
or The Profiteer creates the connection to the gold and the way there isn‘t blocked
by a door of the other color
