I don't think this means that your medicals are clear. They have just received it and you will get notified if you have any medical conditions. You will be requested to submit your Passport if everything is alright within 30-60 days.
Congrats on your MR. I have been requested to send copy of all pages of valid passport by mail or email. I did my medical on 12th May 2015 but have not received any information yet. Please keep me updated about your status.
