I don't think so. Updating on line doesn't mean BCIS updated your file.
I did early fp2 on July 17th. Online never get updated. When I checked with immigration officer (Local BCIS officer) told me that my file got updated on the same date. Told me, not to bother on line message.
One of my friend did early fp, his on line message got changed right after 3 days.
Don't worry, go ahead and do early fp.
