What's the difference between these two pieces of simple code?

Do you think there is a difference in functionality between these codes? always @(posedge clk) begin A<=0; if (sel==0) A<=in_u; ...

Ill just clarify:


always @(posedge clk)    
begin
  A<=0;    
  if (sel==0)
    A<=in_u;
  else
    A<=in_v;
end

is identical to this:


always @(posedge clk)    
begin
  A<=in_v;
  if (sel==0)
    A<=in_u;
end
