I think I heard something similar when they first laid the pitch. I think the fibre element is in the seed/growth though.
And no I don't understand that either.
Not seen it discussed anywhere else but who else was gobsmacked by the quality of the turf! It was like being on astrotruf. I doubt it hardly suffered any damage at all.
When I look back to similar occasions on the pitch at the Goldstone and Withdean the pitch was never as good as that.
Well...
