Default Depreciation Rules

Can I have multiple default depreciation rules for an asset category and will depreciation be taken for assets within the category based on the Placed In Service dates associated with the rule?

For instance - Category A has the 100% bonus taken for assets placed in service between 09/08/2010 and 12/31/2011 and 50% bonus for assets placed in service after 12/31/2011. So today; February 10, 2012, I add 2 assets in Category A. The first has an in service date of 12/31/2011 and the second has an in service date of 2/10/2012. I would expect the first asset to be depreciated with the 100% depreciation rule and the second to be depreciated with the 50% rule. Is that correct?
