Coefficient Multiplying Laplacian Implicit in Neumann BC?

I'm solving the parabolic equation:
I set up the PDE as:
specifyCoefficients(model,'m',0,'d',1,'c',D,'a',0,'f',0);
and the Neumann BC as:
applyBoundaryCondition(model,'neumann','Face',1,'g',zeros(1),'q',k/D);
However, reading the information about the Neumann BCs on the webpage below, I am wondering if Matlab automatically uses D in the boundary condtition because it is the coefficient c in the equation set up?? If this is the case, would I just use??
applyBoundaryCondition(model,'neumann','Face',1,'g',zeros(1),'q',k);
