Correct. Look at the original poster for example. He was on his way to a 6-0 and the other healer left to prevent that. If they were forced to remain in the lobby then:
- They would be more likely to play it out just knowing they had to be there anyway and they would at least have a chance of avoiding the 0-6.
- If they just stood there idly then the 0-6 happens just as it was likely going to anyway (hence why they stopped playing).
