Is wrfchemi for parent domain used in area of nested domain?

Hi!
I want to run WRF-Chem with a passive tracer (chem_opt = 17) and two-way nesting (feedback = 1). Regardless of the nest configuration, the chemistry input files (e.g. wrfchemi*d01) have fluxes for the tracer specified over their whole domain, i.e. including the area where the nest is. The chemistry input files for the nest (e.g. wrfchemi*d02) of course also specify emissions there. Hence my question: are values in wrfchemi*d01 that fall within d02 used? I.e., could I set them to arbitrary values without affecting my simulation?

For reference, I eventually simply tried out what happens when I change wrfchemi*d01 in the area of the nest, and the atmospheric tracer output was the same. The changes were not close to the boundary.
