At least they went around I guess!!
That also makes it even more scary, it is not a go-around, but a touch and go. Touch and gos in an airliner should not be a common thing, and it is certainly much more dangerous than a regular go-around.
I can't believe they did not drag the tail on that one, it looks extremely close to the ground towards the end, although it could just be the poor lighting. I would imagine trimming while in the flare and then adding boat-loads of thrust is just a recipe for a tail strike, especially with the underslung engines. You suddenly find yourself pushing on the yoke to control rotation rate, which is the opposite of what you are doing on a takeoff.
Normal in a go-around, but when airborne you at least have a little more playroom to overshoot and correct back down - not so when inches above the tarmac.
