Allen didn't know how he survived those two minutes. Two minutes may seem short, but for an extreme operator, it's incredibly long and torturous. This lengthiness isn't about game control; Allen had to maintain his stance without moving and think about his combo changes for the moment the pause time ended.
Of course, this is just one aspect. After all, two minutes are very torturous for his current state, but not unbearable. The most unpredictable thing for Allen was that Feng Yi's treacherous moves were endless, countless, and as numerous as cattle, ever-changing, leaving you unable to predict when he might press the start button next.
Allen would never pin hope on waiting until the 59th second. Suffering leads to learning, and he had already suffered twice in silence. He knew well that Feng Yi might press start at the point when he waited the longest, or perhaps a second earlier, like at the 58th second, or even less time.
