Yes, threads which are inactive in past 120 days get archived.
OK, thanks for the info. I guess I see now where my confusion stems from:
The last reply in a thread is not necessarily the latest reply.
For instance, the last response of a thread may show a date that is completely different than the date of the latest reply shown in the header where it displays the total number of replies and page numbers. Apparently editing a response changes the date of the latest reply, which affects the archiving policy. Threads are however listed in the order of the last and not the latest reply.

If users are posting new replies or editing existing replies, Such latest activity will be the last active date of the thread. So, editing a response also makes a thread active.
