Why does the CFD results change with different initialization techniques ?

I have recently observed that the CFD results shows significant variations with different initialization techniques (mainly standard, fmg and hybrid). What could be the technical reason for this...

Does 'symmetry'and periodic'boundary conditions in CFD (Fluent solver) behaves the same?

Even though theoretically 'symmetry' and 'periodic' boundary conditions are totally different, i found that the CFD results with either of them are very similar. Why it is so ?
