Multiple rand references to the same object

SystemVerilog
1 
class A;
   rand B B1_h1;
   rand B B1_h2;

   function new();
      B1_h1 = new();
      B1_h2 = B1_h1;
   endfunction
endclass

A a1 = new();
a1.randomize() with { // B1_h1.member constraint };

Will the constraints to B1_h1 also apply to B1_h2?

Yes, there is only one object.
