Nope. Sphere effects are an AoE that affects everyone... except the wearer. Don't ask me why. Please. It makes my head hurt.

The RDM AF3+2 set bonus is also a direct response to the constant complaint of, well, 99% of RDMs in existence who felt that their single-target buff cycles were absolutely ridiculous and needed to be fixed. I mean, if you never cast Haste or Refresh on the rest of your party anyways, I guess it doesn't really do anything for you. But, you know, for those of us that actually do enhance our fellows, it's one of the best Set bonuses out there.
