Why should you? Think of it this way. If you wound the primary with wire 
of twice the cross-sectional area, there'd be mo problem, right. Now 
split that wire into 2 separate strands, conenctinf them together all 
along their length. It's the same thing (the shape of the wire doesn't 
matter). Now, since corresponding points on the 2 stands have the same 
voltage on them (at least to a very good approximation), you can remove 
the connections without affecting anything, just leaving them joined at 
the ends. You've now got 2 separate coils in parallel.
