In your example they serve no purpose.
Most likely the code was designed to accommodate various options that may need to be included in the brackets via macro variables. If no options are present it would resolve as in your code.

The actual code in the attachment is
data LASRLIB.iFinIncomeStatement ( );
set TEMP_LASR_VIEW_6296 ( ) TEMP_LASR_VIEW_6696 ( ) interimTable();
I suspect someone previously just had () for data set options for testing the code, just as to pull in just one record.

These brackets have no function if empty. I was actually not even sure if it's valid SAS syntax but I could execute such code without any issues.
data temp (keep=var1 var2 );
set table1 ( ) table2 ( ) table3 ( );
