EPTThis may looks like a lot, but not if you consider that TOP's cheese was really allin. Proxying the barrax, that's a loss of mining time, plus he had to slightly cut scv for it. Then, he send 5 SCV out of 14, that's a huge deal.
Then, he had to fly his barracks to his main. Huge loss in production time, he couldn't produce marines, had to make bunkers etc....
TOP simply pulled back without doing the damage he needed with his cheese. Just look at the supply, they are even when he pulls back. Their economy is probably also even. But zerg has complete map control and is allowed to secure 2 base while denying terran's expo.
TOP made 2 mistakes: pulling back without doing enough damage to compensate the cheese investment. Not scouting after pulling back and blind countering a banneling bust that never came.
Another way to see it: 5 workers not mining during 3 minutes, that's roughly 5*3*40=600 mineral lost. It completely compensates the unit loss of Losira. The only problem for zerg at this point is the lack of production, which is compensated by the double expand.
