As long as this is open code, it doesn't have any effect. The subsetting ends with the first semicolon, the asterisk indicates that the rest of the line (up to the 2nd semicolon) is a comment.

Comments in SAS can be of the form
Now all this is extremely abbreviated and subject to omissions/errors that my fellow peers will eventually point out.
What it boils down to in the context of your question:
The "bold statement" is nothing but a comment that tries to explain the non-bold statement (ie. the subsetting if) to its left.
Hope this makes sense
