Juan does a fairly good job of explaining the phenomenon in this video.

He is very clear in his communications that we are in a dynamic game of chess with pieces on the board, possible moves and counter moves in the future, and that we are playing a waiting game as to who will move which pieces first.

He mentioned in this episode how there are a lot of folks out there who are looking for a "gotcha" moment to discredit him. They want to pin a date on a prediction of his, and when that date comes to pass without a happening, use that non-happening as a character attack to prevent others from looking into what he is discussing. It is a cheap tactic, and one that Anons should be able to see through at this stage in the game.

Juan never discusses events in relation to dates. He always discusses events in relation to the moves and countermoves available on the chess board. What he talks about today may not come to pass this week, or this month, or even this year. He is simply laying out a possible avenue that the Deep State and Cabal might take going forward.
