Transactions that didn't make it into the post-reorg chain go back into the mempool and miners attempt to reinclude them: this is the "merge" process. If they now conflict with other transactions they are dropped and this is "resolving merge conflicts".

If your software is programmed not to do that out of some bizarre belief that throttling your own user base is a good idea, then of course, no merge happens. Once you stop telling your computer to do that, you can then merge (reorg) back onto the main chain again.
