What does 1周まわって mean in this context?


Context:

Person A is a modern person who was transported to a parallel world where
people are still in the middle ages. Person A assumes that the present Earth
is round and he explains to person B that it is a magnetic sphere with a north
pole and a south pole. Person B neither knows about this nor believes in it.

Person B: 世界は玉じゃないよ

Person A: **...もう1周まわって そっちが真実かもしれんな**

The conversation ends here.

Now, I can't make sense of the last sentence. Who possibly could do the 回る
here?




It's used when you accept something even if you don't think it's honestly
good, such as when you think "that's weird" but you can't help yourself
laughing because it's funny.

The phrase "一周回って" can be used to acknowledge a comment that would generally
be regarded as bad, but statement is still so to the point that it makes
sense.

The phrase "一周回って" is used in the same way as the slang term "逆に". It's not
strictly "逆", since 一周(roundabout) = 360 degrees and 逆(opposite) = 180
degrees, though it's a well-established usage.

Side note: It's also used to say that you have come "full circle".

For example, let's say that you liked Girl A at first, but then you changed
your mind to Girl B and stayed away from Girl A for a while.

But when time passes and you looked at Girl A again, you feel that she is good
again. When you look at other girls, but you still like Girl A, you say, "
_一周まわったけど、やっぱりAが好きだな_ ".
