It's a bit dubious for how much of a difference it makes. I haven't actually worked on any of the buff addons, but my impression is there isn't an API for any short-term buff/debuff. As such, they need to watch for essentially local keypresses and start a timer locally based on it.
For example, if you cast a buff skill then cancel it (with block) before it actually goes into effect the buff still shows up. Probably the easiest to try this on would be something like templar's Dark Flare b/c of the cast time.
If it's using a local timer of that sort, then it's already doing as best as possible for when you should reapply the buff. Of course, if your ping varies a lot, it'll be off, but that really can't be helped.
