Two resources to look at are: 1) Wikipedia "Linux MD RAID 10" http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10 2) mdadm manpage section for --layout= (the raid10 part) "Finally, the layout options for RAID10 are one of ’n’, ’o’ or ’f’..." The key to understanding your setup is mdadm --detail "Layout: near=2". The cited Wikipedia reference for a "standard near layout" describes your situation.
