What vger99 showed you was in short form a fundamental mechanism for regexps, which is mostly unknown and/or not used to its full capability:
This will perform command 1 through command n only to lines, which match the expression. The expression itself does not necessarily have anything to do with the operations performed, it just acts as a filter to decide, onto which lines to apply your commands.
So his sed-oneliner reads in fact: "apply to all lines containing 'setmqaut' the following: replace the end-of-line ('$') with the string '>> ...'"
The a-subcommand gets used only, when you want to append a certain piece of text after a complete line.
