It's not opinion, my friend - I don't think you understand how it's supposed to work. As mentioned in the text I copied and pasted, the trigger's purpose is to allow you to set two threshold voltages - creating a "window" in-between - and then have the DSO trigger if the signal enters OR exits (OR either) that "window". In the given example, monitoring a 5V power supply for positive and/or negative excursions outside the range of 4.5 and 5.5 volts.
This is exactly what the Rigol's Windows trigger can do - albeit hopefully with some changed names in a later FW ;)

As far i read all the info, it has to be T2 AND T1, but your interpretation is T1 OR T2, oke that makes this topic more simple
see if i can find more on it.

The folowing test, to see where i am wrong,
Picture 1, T1 and T2 above, no trigger possible
Picture 2, T1 and T2 low, perfect trigger
( rise and exit on. )
Why is there no trigger possible in picture 1.......

Why would it be T1 AND T2? How would that help in the given example of looking for power supply fluctuations? It has to fluctuate both up AND down? It makes no sense.

There is no real "RISE" - it's TOP WINDOW - and your signal is never exiting the top window.
