[Avid-L2] Does Rendering a Matte Key Graphic in After Effects to DNX invert the alpha channel?

 

The vast majority of graphics I get from After Effects are at RGB level and I invert the alpha on import and everything works fine.  I inherited an AE project for a series I'm doing and I created an export setting for Avid DNX 220 with Alpha straight key.  I find when I import these graphics I don't have to invert the alpha on import.  I'm curious why they aren't like most AE graphics I get.  Does AE know to invert the Alpha channel when exporting to Avid DNX codec or is there just something about how the AE project is handling the alpha that is inverting the alpha before it gets into Avid?
