The rest of the quote goes like this :
"....really did write something here about Jesus, but that the text that has reached us is corrupt to a perhaps quite substantial extent. In the words of the Catholic Encyclopedia entry for Flavius Josephus, "The passage seems to suffer from repeated interpolations." There has been no consensus on which portions are corrupt, or to what degree."
Corrupted, interpolated, forgery.

So, -1- account by Josephus in which we have proof it was a forgery. Josephus may have actually wrote something of Jesus, but it was tampered with and corrupted.
Secondly, the place where the mention of Jesus actually shows up, is in the early 90's CE but NOT in the earlier "The Jewish War".
This is to be taken as he had no idea who Jesus was until he heard about him from religious people many years later.
