Well, he asked & I'd seen the answer once before, so I researched it for him. As a FE for one enlistment, he'll more than likely will get over 1500 hours. Thus, he can apply 500 hours towards his ATP. While you may find it strange that anyone would be given any real consideration for his FE time, I find it strange that someone with only 1000 TT would make FO on a 747, at least in this job market.
Happy landings,
