I have looked at it and I can't say that I can see what you say. There is something there but its too low a resolution to be sure.
The other picture I have seen has someones head in the way.
He's got a hard hat on so he's alright.
Save the picture, and blow it up, you can see the bright bit, which in itself isnt definately the leg, but if you look above it you can see the dark shape of the rams body (compare it to the other side, you will see it is a pretty close match) Also, if you look to the left and beyond the left side light cluster, you can clearly see a garden gate, and the greenery (lawn?) behind it, if the leg was extended, that is where it would be, it would be blocking the view of the gate and lawn.
