check while adding multiple fields with same name in same register

[piyunaffi]

While looking at the code of function:

function void uvm_reg::add_field(uvm_reg_field field);

in uvm_reg.svh, I see that there is a checks for overlapping fields and if filed size is more than what register can accommodate but I do not see a check if name of field is same.

Such check is there for registers in add_reg function in reg block.

Is there any reason?
