But which result is used by the dataTable - the last?

All of them are used at different times.   It's going to be
internally-inconsistent and probably cause problems.

You need to use a caching pattern:

private List cachedList = null;

public List getList() {
   if (null == cachedList)  {
       cachedList = fetchList();
   }
   return cachedList;
}

Then, depending on whether this bean is request, session, or
t:saveState scoped, the list will be refetched once per request, per
session, or per page.
