Is my orthodontist right? (Photo)

I got braces 2 months ago, to close my gap and straighten my teeth He has crossed over the power chains in the front ( he said making the X shape will close the gap faster) is that normal? He gave me elastics making a triangle shape but from my research they say it'll bring my top teeth backward and my lower teeth forward - I hate my lower teeth protrusion so im really confused my he's bringing my bottom teeth forward the more Do I need to change my dentist,starting to think this one is clueless
