That sounds good- I wouldn't worry.
My older one at 10-12 months would follow directions like "go over to the door" (told without pointing). He talked early but later than when he followed directions- we realized that his receptive skills were very early and were obviously ahead of his expressive speech skills.
I'm sure there is a delay between their motor skills coming in and their understanding. You could teach him baby sign language. Our kids did that, and it's really helpful at communicating with them when they can't quite get the words out.
