What is the exact meaning of the implications of the word "Acharei, Derech M'vo ha'Shemesh"?
Rashi: Because (as opposed to 'Achar' which means near), "Acharei" always means far (either in space or in time).
Rashi: "Acharei" is not directly connected to "Derech M'vo ha'Shemesh", as idicated by the Neginah ("Acharei" with a 'Pashta', and "Derech", with a 'Mapach' (which Rashi calls 'Mashpeil'), instead of the other way round. In addition, the 'Daeld' in "Derech" has a Dagesh. See Rashi in Sotah, 33b DH 'Acharei Derech'. See also Rashi there DH ' ha'Lo Heimah'.
What are the implications of "Mul ha'Gilgal Eitzel Eilonei Mamrei"?
