This is really about 'modality', I'd say. If you have statements in the past that were about the future which now is already past, these statements can usually be verified with certainty. Like a weather forecast. This 100% certainty however breaks down, if you move the forecast far enough that it touches the "real" future from our current present. E.g. you have to observe the weather to see if the forecast was true. So this "paradox" is just about how the modality of the statement changes discontinuously once it is really uncertain.
