So far I got,
- The flour gives somethigng that egg can stick too
- The egg wash layer acts as something which the bread crumbs stick too
But, why mix in the mustard to the egg? Couldn't the egg wash directly stick to breadcrumbs?

Mustard has an intense flavor and is therefore generally added in quantities that have very little effect on consistency, stickiness and similar things. Your recipe aparently wanted to introduce mustard flavor. If you agree keep it in, otherwise you can leave it out without any further adjustments.
