Other mistake: When the shuttles dock we see a close up of one docking, on the side of the shuttle is the hatch which completely misses the docking arm but we hear the sound of it making contact.

Chosen answer: His comments to Drax were about the physical and mental perfection that Drax required for those chosen to repopulate the Earth. As Dolly (Jaw's girlfriend) needs glasses, she falls short of those criteria (as, quite probably, does Jaws himself), which makes him wonder whether Drax won't simply get rid of them once he's carried out his plan. As such, he chooses to ally himself with Bond rather than risk Dolly being harmed.
