It's not better but for a different purpose.

SAME-AND Operator
Use the SAME-AND operator to add more conditions to an existing WHERE
expression later in the program without retyping the original
conditions. This capability is useful with the following:

interactive SAS procedures

full-screen SAS procedures that enable you to type a WHERE expression
on the command line

any kind of RUN-group processing.

Use the SAME-AND operator when you already have a WHERE expression
defined and you want to insert additional conditions.
