Export (beta): Match Source settings are incorrect

In the Premiere Pro (beta - 15.0), using the Export panel, Match Source - and all the High Bitrate- settings convert the sequence into H.264. 

This is incorrect. Match Source should use the same codec that the sequence uses, otherwise, it would be impossible to export a high-quality master file. (Well, not impossible, but we shouldn't have to tell Premiere that H.264 is not matching the source.
