The double email entry makes perfect sense if you accept the following base assumption:
The designer of this form is the Kwisatz Haderach! He sees all of your potential futures laid out before him, almost as if they were lines on a whiteboard. To him you are not a person filling out a form, you are a quantum of potential revenue in a treacherous maze of possible outcomes. He is afraid, because he sees many many futures in which you simply cease to exist - your potential collapses to $0. There are a precious few paths where you survive this peril, and every single one begins with you typing in your email address correctly. A password can be recovered, but you can not.
It other words, this form is for quanta of potential revenue, not people. Don't forget the quanta pay the bills though.
