Date Format mm/dd/yyyy not working during import for contacts

In CiviCRM v3.1 beta 4 with CiviEngage install, and also tested in the CiviCRM sandbox (CiviCRM 25758), when importing a date format of mm/dd/yyyy and select this format for import, in the following import screen, when you can view the data, I see that civi shows the date format as mm/dd/yy, which then causes an error when trying to run the import. This is confusing to the user - of course if I go back a screen and change the date format to mm/dd/yy, it works. But definitely a usability issue, since a user expects their data to be in mm/dd/yyyy.
I also noticed that in the Global SEttings -> Date Settings, the option for complete date is "mm/dd/yy (12/31/2009)" which is also confusing to the user. I think in previous versions, we actually have mm/dd/yyyy when selecting a date format in the import and it works wonderfully.
Is this an intended change for v3.1?
