Well it should but it is not in reality. On most "electric" guitar you 
have the availibility to change the lenght of the string at the bridge 
(intonation tuning) in order to have the first harmonic of the string in 
tune with the note fretted at the 12th fret. This is not true on 
acoustic (folk) or classical guitar where the bridge is fixed. In fact 
the position of the frets should depend on the diameter and the nature 
of the strings in order to have a perfect tuning. I have seen a high-end 
classical guitar where you could slightly change the position of each 
fret for each string, in order to have a perfect tuning !!
