Enable right menu in split-view

I have an app that uses a left side menu and I am using the split-view option to expose it when in landscape. However I noticed that when the left menu is exposed in landscape the right side menu is disabled and not accessible. Is there a way to bypass the disabling of the right menu while the left menu is exposed in split view. I am sure this is by design I was just wondering if it was disabled for performance issues or something else.

Thanks,

Anyone able to provide insight on this?
