Yes, questioning the authorship of books of the Bible could make him a heretic. I'm not up on what all he believes, mostly I know that he was a disciple of famous Bible scholar Metzger, known as an unbeliever, who refused to accept the book of Daniel as prophecy etc.
If Origen taught reincarnation certainly that makes him a heretic. And Alexandria is known as a place where heretics flourished in the early centuries. That's one reason to doubt the "Alexandrian" Bible manuscripts that were "found" in recent times and are now used to replace the authentic manuscripts, which is a great fraud on the Church. Dean John William Burgon said this type of manuscript with many omissions of famous passages as well as altered words, was known to have been altered by early heretics such as the gnostics. They were rejected for years until a couple of heretics foisted them on a very naive Church in 1881
