I have been thinking and reading.. and this is my guess right now:
1) The plastic black matrix serves as air-straightener, like a honeycomb-mesh.
2) The fine metal screen after the black matrix is a extra protection for debris that might have got past the air filter, protecting the MAF and engine.
Thus removing the metal screen would give less air flow resistance but less protection of MAF/Engine. I cannot see how the metal screen would smooth out air pulses, but what do I know?
I have seen others that replace the plastic and metal screen with a honeycomb with far less area, thus giving more flow. This should be a good thing in my book.
EDIT: @Maytag, please let me know if I´m destroying your original thread, that's not my intention.

If the mesh is just before the MAF sensor it is there for the purpose I stated. To smooth out air pulses.
I got the information from an article I read on MAF sensors. The article was by Bosch. They developed the first MAF sensors and also the first O2 sensors. So I tend to go with their information on those two sensors
