I understand you only want the outer surface to be masked and extracted?
Checking Brush->Auto Masking-> BackfaceMask will disable masking on both sides simultaneously, a mask will then only be applied where you actually mask (+symmetry if active).
Remember to hold Ctrl while selecting this option to apply it for your mask brush. Otherwise it will only be applied to your topologybrush.

In the Extract palette, turn off the “Double” button.
