Exactly! It is quite obvious that they are talking about the rook moving from its original starting position. But it does leave some wiggle room for some funky interpretations. Interesting, and shows you that you never know what you think you really know :D

Did you know that until 1903 you could skip promotion and let the pawn rest on the 8th rank?

This would have been useful in this position:

[d]K7/pP5r/k7/8/8/8/8/b7 w - - 0 1

Only 1. b8=P! would give a draw (stalemate). Any other move loses.

... as putting a piece on the board during the game (by promotion) is moving a piece as well

It can be argued that Rook did not exist in the opening setup. It came iinto existance only upon promotion of the pawn and therefore has never moved (yet). :)

Sure, there is a very far-fetched interpretation, which made the rules slightly ambiguous. Which is why the wording was changed.

But the act that the rules could be disputed with virtually zero chance for success is really very far from that it would have been allowed. It was never allowed, and the wording was changed to remove the illusion that it might be.
