There are many problems with this, if you try to explain it in a rational way. Another bit that is never cleared is why Joker is in the Mass Relay. He cannot be in FTL, else he would not know what was happening anyway (ME is very clear on this, you have no faster than light sensors or anything like this). So if he was in FTL, running towards charon (Which takes 5 Minutes, if the Normandy SR2 can indeed fly at 24ly/day) he cannot be aware that anything is happening at all, nobody onboard the Normandy knows what Shepard is doing. They'd also never see the explosions, until much much later.
If he only starts to fly once he sees the citadel is exploding, he's already way too late. The "colour" explosions move much much faster than light as well (see last video) so by the time Joker would actually see the wave as portrayed in the video he'd already have been hit 2 minutes ago. There is simply no way to make it fit, unless he has a time machine in his pocket.
I'd chalk it up to space magic.
