That's stupid, ask any orthodox jewish scholar, or hell, read the passages yourself. The first section is 'foreshadowing' for lack of a better term, and the second is the accounts in detail.
They're not exactly the same. Genesis 1 places the creation of animals before humans, whereas the natural reading of Genesis 2 has the reverse:
"And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them"
(Admittedly some modern evangelical Bibles make this "God had formed every beast". But this seems to be motivated by a desire to harmonize rather than honest translating.)
We should probably distinguish between two levels of explanation: The religious explanation, and the historic/scientific explanation.
The "foreshadowing"-explanation is a religious explanation. The historic/scientific explanation is that the two versions are from two different oral traditions that have been merged into the same book. Both kind of explanation are interesting, but they are also largely incompatible, and I think it always should be made very clear which perspective one is arguing from.
