Quite thorough. I'm sure the soapy water will get rid of the encrusted mud in those pictures, but I would do as in step 10 in those instructions and take a toothbrush with solvent or degreaser to all those parts.

WD-40 or other spray on general purpose lubricant+solvent sprays while terrible for lubing chains are great for cleaning those pulleys and other light degreasing jobs, very cheap as well and useful around the house too.

It is so cheap that I don't agree with the advice given there of using hot soapy water to reduce costs... I mean it might be better for your health to avoid contact with (harsh) solvents, but given the total ineffectiveness of hot soapy water in getting my hands clean of bike grime even with thorough scrubbing vs a touch from a $3 tub of mechanic's hand degreaser, I am unconvinced of its effectiveness in getting tiny mechanical parts squeaky clean...
