Typically we do not discuss things in their past state. If we convert a library to an office, we do not say "this is a library". When a human turns 21, we do not say "this is a baby". Although previous states are interesting, they do not account for the changes that have occurred. What would be the point of transitioning to anything if not to become that thing? That's the very definition of what it means. You transition, then the state has changed.
