tracking in Motion

[Vultch]

I was just watching a tutorial vid on Youtube,

The scene is a fairly steady handheld pan across a landscape, the editor wishes to attach a lens flare that tracks.
The first thing he did was to stabilise the shot, then he tracked a point in the scene and added the flare to it.

My question, why stabilise the shot, what advantages does this offer, considering its probably the same algorithms why not just go straight for the tracking function and add the flare.

Thanks

Maybe he wanted to make the shot more stable overall? Post the tutorial for reference.
