Maybe you wanted to say, "If there is a present time, any time beyond that is future time". But you didn't catch the meaning of "overlap". After your saying, I may also add a present time AFTER your future time:
Ex: "If there is a present time, any time beyond that is future time, and any time beyond that future time is present time".
For example, if "this week" is present time, "next week" is then future time. However, after "next week", there is "this year". This is what I mean the present time is overlapped with the future time. In other words, the two kinds of time are confused.

I didn't say there is no present time, and there is. I didn't say there is no future time, and there is. But the two kinds of time are overlapped, so cannot be a criterion to judge the Future Tense. Future Tense is then judged by uncertainty, rather than by future time.
