Google SEO logic is always a tightly held secret, but moving your domain can/will always result in a lower site ranking. By having the auto forward setup the way you did you might be effectively giving Google two sites (so far as it knows) to keep page rankings for, and as a result your ranking will always be lower if it is being divided among two or more domains.

This is always the result when you move a domain anyway. As a service to your viewers it is your responsibility to make your best effort to keep any bookmarks they may have had valid for as long as possible... which you have done.

I have the suspicion that Google will tell you that what you are doing is correct as it is in your viewers best interest to keep your site functioning in the manner that they are accustom to. However you may be in the gray area between providing good service and using the best SEO.

Living in the gray area between good service and good SEO is not a bad place to be if you think of it as the best of both worlds. Google is pretty smart, and it is only a matter of time for any loss you had to be corrected so long as your site is still servicing your viewers and they are still coming to your site, no matter how they are getting their.

Another option that might be available to you through your host is to autoforward blog.yoursite.com to yoursite.com as a wildcard forward. This will have the same forwarding effect you already have, and it should/may also give Google bots some feedback as well.
