Exactly you can use it for example when you have a sql file that need to be executed for many database by php, you can retreive all queries with this class and you can execute them.
It's simple but usefull

Many times when you update a softare you have to execute customs queries vs. many differents databases.
With a sqldump you can execute and import a backup, but if you need to upgrade for example 100 databases stored into the same server for exaple to alter a table, update some values etc, with this script you can store a simple sql file and than use a php script to execute all queries for all databases.
