@Cambriouleuse the clicks that matdas provided in the 2nd ban were different clicks. The original click was a smart order and as BouncingHitman explained was not solid evidence, the selections inside of the fog of war however were pretty clear evidence. I have not actually watched the replay to see if he had vision of the Swedish Lumber Mill but I am assuming that the clicks were made inside fog of war.
EDIT: These two clicks
17:41 <tyuky147> 0x19: Select subgroup: [Swedish Lumber Mill], 0x0000397800003978
18:02 <tyuky147> 0x19: Select subgroup: [Swedish Lumber Mill], 0x0000397800003978
seemed to be the deciding factor.
