How do you mean by disconnecting? As in casting my hands out away from the shoulder?
No... I think your line to the ball looks fine. Your hands always have to come away from your shoulder at some point so it is more about the timing of when you make the final delivery of the hands. The longer the connection stays the shorter the swing path.
Take a look at this video. It is not intended to demonstrate this particular aspect of the swing but what you will see is a strong hand connection until his shoulders are well into the swing
Anyway, like I said this is an opinion at best. If you are really troubled by it you need to have someone with good high speed diagnostic video (like in the attached) to see if my perception has any value to you. If not then you totally got your moneys worth
