Re: Not late.
Strictly speaking that wasn't really a suicide burn - they entered a full hover and squirreled around before landing.
A suicide burn (or a hover-slam as SpaceX calls it) is where your vertical speed must hit zero at the precise moment you touch the ground. So named because if you're late on a suicide burn you'll hit the ground too hard, and if you're early you'll come to a hover and then take off again (or finish your fuel and fall the rest of the way). Either way, there's probably going to be an explosion.
Falcon 9 has to do a hoverslam because they can't throttle the engines deep enough to actually hover. When it's near-empty, just one engine throttled down as deep as it will go is generating more than 22tonnes of thrust (22tonnes being about the dry mass of a F9 booster).
Because New Shephard is a sub-orbital plaything they're using a much smaller engine in relation to the vehicle mass, which can throttle deep enough that they can balance the Thrust-to-Weight at zero and hold a hover (for as long as they have fuel! And they can carry excess fuel since they're not trying to do anything useful like go to orbit), which appears to be what they did there - got down to a hover, held for a moment, then made the final touchdown.
