The most recently generated ID is maintained in the server on a per-connection basis. It will not be changed by another client. It will not even be changed if you update another AUTO_INCREMENT column with a non-magic value (that is, a value that is not NULL and not 0).
So as long as you're using non-persistent connections, even on a site with heavy traffic it should work fine.
