Thanks Andy and Blair. I've already understood this part explained on
manual so my doubt is considering that a working copy was created and
populated before, it will only receive changes (never it will send or
commit them) and aI will not modify he URL.

Considering those points. Will the behavious of both be the same or
there are any risk of happen something wrong?
