It seems to me that a factory pattern is exactly what he is doing here.

Not to quibble, but no, I don't think that's what "factory pattern" means.

A factory hides the mechanics of constructing new objects behind another interface, whereas all of the instantiation done in this example is explicit.

I'd say the OP is showing a behavior composition technique, like the GoF's Strategy pattern, expressed in proper Perl idiom.
