Perhaps they thought the school may have attempted to correct the scheme's insufficiencies rather than simply end it.
The problem with an all or nothing scheme is that it doesn't encourage those who know they cannot reach the all so they might as well go for the nothing.
More graduated rewards would push those who cannot come first to at least still aim for second.
