I guess they might want to avoid some abuse of people switching to DOL to sneak, then switching back to DOW or DOM after gathering at a place past enemies, but I don't really see this as being a big deal. The sneak speed is much slower than is was in 1.0 though, from what my experience with it has been so far, I'd be happy if they made the sneak penalty about where it was back in 1.0.
