The Voice US has been doing a Twitter save for several years. The final 2 seasons of American Idol had one too. The difference was that that the acts not saved didn't go to a sing-off. The sing-off was before the instant vote. The loser(s) went home directly.
The AGT save wasn't for the B3, it was for the the mid-pack. For example, if 12 performed, only 6 went to the next round. So the T4 were through. The B5 were out. The 5, 6, 7 ( without revealing the order) were eligible to be saved. Then the remaining 2 were eligible for a judge save without another performance.
