This isn't a flipper disc. You're not paying attention.
The Blu layer is closest to the surface, and two DVD layers are deep in the disc. The Blu layer is "transparent" to the DVD wavelength laser, which passes right through and sees the DVD layers. The Blu laser reads the Blu layer only, and doesn't even know that the DVD layers exist.
