This has no impact on performance right?
Who knows. Probably not noticable.
The direct impact of geomorphing should be nearly zero. It's just a bit of extra code in the vertex code.
But geomorphing will does have a direct impact on visual quality. You are bringing the LOD transition closer, just so you can fade the transition over a wider range. If you choose to compensate for this loss of visual quality by increasing the LOD transition distance, there will be an indirect performance impact.
Seams may be missing, which may be exacerbating the lod transition, as reported here:

As the LODs move across the terrain there's a slight shift. Mike Savage said this could be resolved with geomorphing, which will create a smooth transition from a high resolution mesh to a low resolution one.
