Inaccuries in topic for ALTER DATABASE File and Filegroup Options by Erland Sommarskog

Under FILENAME 'filestreampath' it says:

    The filegroup and file ( <filespec>) must be created in the same statement.

This is incorrect. You cannot even have ADD FILEGROUP and ADD FILE in the same statement, and example I uses two statements. Also, note that in this example "database" is in lowercase.
