If you did the form online and have written confirmation/proof of having done it, I believe you're all set.
To explain how it relates to both your current and upcoming status, the USCIS change of address information page says that if you are changing address in the US and you have an application pending, then you must:
Step 1: File Form AR-11 (online OR by mail);
Step 2: Change your address on any pending or recently approved applications or petitions, online OR by phone at 1-800-375-5283. For TTY (deaf or hard of hearing) call: 1-800-767-1833.
Use our convenient Online Change of Address system to complete steps 1 and 2 at the same time. Once you complete Form AR-11 online - the system will also provide you the opportunity to change your address on any pending or recently approved applications. If you use our Online Change of Address to complete Form AR-11, you do NOT need to file a paper Form AR-11.
As I understand it, this means filling the online form is sufficient.
Lastly, if you have a lawyer working on your green card application, it's worth checking with them, as they will have recent experiences of the reliability or unreliability of changing one's address with USCIS.
