Bounces are bad news on airliners because you are becoming airborne again just as the lift dumpers pop out, which makes the second touchdown even more exciting and often leads to hard landing inspections, and in extreme cases broken gears.
The lift dump spoilers are supposed to limit bouncing tendency, but if you come down hard enough there is so much energy stored and released they don't come out fast enough or they are ineffective initially when they do or on some airplanes they won't even be triggered until the nose wheel is down.
When you have a significant bounce on a jet you aren't supposed to try to save the landing. It should be "go around - set thrust" and get out of there. It's called a "Balked Landing" which is a go-around initiated in a low energy state close to the ground. You MUST get the lift dumpers retracted, or prevent them from coming out, and setting go-around thrust will do that. You may touch down again and probably will, but you are supposed to continue with the go around.
There was an Air Canada Jazz RJ that bounced on landing and they tried to save the landing, but the bounce was so high and the lift dumpers were out so they collapsed one of the main gears on the second landing.
Like everything, there are nuances; a little skip, maybe only one gear touched, maybe they feel a balked landing procedure is more dangerous in gusty crosswinds than just landing, so a lot of crews will try to save it. So maybe this crew did a bad thing, maybe not. Without a lot more details, hard to say.
