No, Sasuke will travel into the real world, our world, and slap all idiots who think he isn't stronger than Naruto. So those who are safe are those idiots who praise his abilities and suck his c**k without breathing in all those pointless threads.
Time is a big part of the story there is no doubt. I have a different theory on how time will play into thing. Your theory makes me curious to check out that other manga. On a side note, if you had introduced this theory a year ago there wouldn't be enough extinguishers to put out the flames you would get. Nice to see folks opening up to the concept a bit.
