Forward movement in Dura Ace Derailleur

While trying to track down an annoying first gear clicking noise I noticed that I can move the derailleur fully forward as in the photo.



My winter bike has a Shimano 105 groupset, and there is no movement either forward or backwards.
So, do I have a problem or is that amount of movement normal?
For reference there is an expanded drawing at,

Thanks and best wishes,

    Thanks Trevor, for clarity, that amount of movement indicates a problem?
