As such it cannot be implied that the the definition has changed nor should people be looking to make such an inference.
This is the problem, though. We don't know why something is/isn't changed from the old lawbook.
All we're being told is "nothing has changed", when that patently isn't the case.
As an example, the 22m line extension question came up in a society meeting a couple of seasons ago and we were told that we were to give the gain in ground. The new lawbook explicitly contradicts that. Okay, not everyone played to that law, but for us it was a change.
And the question of mandatory YCs for PTs. That's explicitly stated in the new lawbook, but we're told it doesn't apply.
It's no use having a lawbook that doesn't contain all the laws, and saying "it's in the old book" is not the solution.
