Dual power supply question.

Does the shared primary winding negate the channel separation benefits of the two output supplies?
 
Thanks. Would there be any benefits at all of the above schematic vs paralleling the two secondaries and using a single bridge rectifier and C-R-C filter?
Background - I already have the Triad tranny and just wondering what power supply config to use for a PP 6P1P amp I want to build.
