There were no fixes performed in the method, the method just gets a product instance from a factory. The comment gives reasons for why it was using a core factory directly instead of using the automatic object resolution mechamisms.

The real method name was getProductInstanceFromCoreFactory. Still long, still clear as to what it is doing. But making the context clear would be more code than it is worth.

Avoiding comments by writing clearer code isn't a bad habit, but my point is that they are very useful to provide context for something that getting context for would otherwise be erroneous or cumbersome to implement.
