As a veterinary doctor, it is ethical for us to comment on the physicians choice of vaccination route and its immunoglobulin production in a person. As a veterinary doctor I can only comment on the dog's health. Usually, rabies suspect dogs are observed for 10 days. If they have rabies, then they will die within 10 days. Since the dog, which bit you is still alive and healthy even after two months, it indicates that the dog didn't have any rabies disease. Hence, you don't have any risk of rabies.

As discussed, both intradermal and intramuscular (hip region) route of vaccine can produce immune response however dose may vary with different route. Please talk to your vaccinator about this. If the dog is seemingly healthy and you have gotten fully vaccinated there is nothing else for you to do here.
