Yeah there seems to be a delay between him pushing it and when the doors come up. But there also may be a little time to push it after the actual countdown goes to 0 like whne Locke experienced it when the symbols appeared on the timer , perhaps the same occured except this time he was somewhere else and witnessed the Map .

"Aim small miss small"

Me, well, I'm a man of faith. Do you really think all this...is an accident? That we, a group of strangers survived, many of us with just superficial injuries? Do you think we crashed on this place by coincidence, especially this place? We were brought here for a purpose, for a reason, all of us. Each one of us was brought here for a reason.
