Chances are, it's probably not the same doe. Bucks will run with does in the beginning of october, and i've seen the same bucks with does a lot, but i doubt its the same doe. they're hard to tell apart unless they're a fairly large one or really tiny. if he is witha doe, an estrous scent isn't going to bring him to you. #1-he already hasa doe. why go for another? Whitetails don't have harems, so it's not like he's going to be interested. #2-if a doe smells estrous scent, she'll probably move away.That's why you'll see estrous does away from the other ones. The does not in estrous don't want to be around her and get dogged and chased by a rutted up buck.
