Stirring does not mean random distribution. Stirring homogenizes a batch, evening out distribution of mixtures and concentrations of solutions.
You'd think that would be right, but mixing, no matter how long, always leaves clumps. This is a known problem in, for example, paint mixing. You can stir for a year, then get out a microscope. You'll see clumps of pigment.
