Mr. Inspector

Maybe someone can explain this to me?
Say I want to build a 12'x 6' deck with the joists spanning 6' from ledger to beam.
2015 R507.7 Beams shall be permitted to cantilever at each end up to one-fourth of the actual beam span.
According to this If I have a two 2x10 beam spanning 8' I can have a 2' beam cantilever on each end.
But if I really want to beef it up and use a three 2x12 beam and add another post between so I only have a 4' span I could only have a 1' beam cantilever.
So if I make the beam stronger with half the span I need to have a shorter cantilever?
