Invisalign for overcrowding will leave me with a 5mm overjet? (photos)

I currently started my Invisalign treatment. My ortho has advised me that once my front teeth are straightened (the two front teeth are tilted inwards) that I will have about a 5mm overjet once my teeth are all aligned. She said that Invisalign can't help with the overjet because I have a good bite. Also, my front and bottom teeth aren't and will not be aligned perfectly because shifting will also interfere with my bite. She said only braces can address these issues. Is this true? Please help!
