Yeah you're getting confused. It's really easy. It didn't format it ext3, it just sets it to a partition type GUID for that filesystem, which in the version of parted you're using is for Microsoft basic data (i.e. it would not have made any difference had you chosen fat32 or ext3, because on GPT disks parted uses the same partition type code until you get to the Fedora 21 version and then choosing ext3 would make it a partition type GUID for "Linux filesystem". Parted is showing it as fat32 because it found a fat32 superblock. When you reformatted it ext3, parted found the ext3 superblock. So again, it's a throwback from when parted did formatting and fs resizing. The behaviors change silently (including flags) between MBR and GPT partition schemes too. So you have to be aware of what partition method is being used. For example "boot" flag for MBR disks sets the active bit for a partition; whereas on GPT the "boot" flag changes the partition type GUID to that of "EFI System partition". Yeah I know, you're welcome to start shooting gin at any time but I guarantee you it doesn't really help. It's sorta like taking Percocet for pain and realizing it still hurts, you just don't care.
