Question on Call COM Server writen by delphi from VB

hello,i have a question in COM program.Can you help me?
I Create a Com Sever with Delphi.It has a method like GetName(out
y:OLEVariant);
when i call it from a client write by delphi ,it work very well.but when i
call it from a client wirten in VB,it work with out return value in the
paramter y.i define y as out paramter,why it not work?
If i change the decalre to GetName(x:OLEVariant;out y:OLEVariant),it work
as expected. while the paramter x is useless.

Does this is a bug in Delphi or VB?
