Definitely. Having Nady on the roster allows the Yankees to further utilize Swisher's versatility, by playing him at 1B when Tex sits and not having to start Gardner/Cabrera in a corner outfield spot. And he'll help when Swisher comes back to Earth.
What I've heard (no source), is that while the distance is accurate where it is actually printed on the fence, in the places in between it is a substantial distance further in.
So the bench began the year as: Kottaras, Carter, Green, Baldelli.
After a few weeks, it's: Kottaras, Bailey, Velazquez, Van Every.
That was pretty fast.
