I think it's probably fine in anthropic's case but I flinch at the "underpromise and overdeliver" line. Heard way too many people say that and what they really mean is "underpromise and deliver."
When you underpromise and deliver sales will still tell you they could have sold the overpromise for even more and should have gone with that.
