It shouldn't have happened. There are force sensors on the pitch trim wheel that signal to the ELACs that a manual pitch trim input is being made. They should immediately resume auto trim once it's released.
Could be that one of those sensors was faulty and the ELAC interpreted it as a THS jam, which will see you end up in alternate law.
