    The OS X 10.9.4 "update", also known as a delta update, will update a Mac that is now running 10.9.3
    That updater will not run on any system, except those that are currently running 10.9.3
    The combined 10.9.4 will update any version of 10.9, including 10.9.4.
    You may ask why you would want to update 10.9.4 to 10.9.4?
    The combined updater will check to make certain that all parts of an update are installed properly, installing whatever may be necessary. That combined updater is much larger, as it includes ALL updated files from 10.9.1 to 10.9.4, plus all the check code to decide what of those needs to be installed.

    All of this means that those are updaters for Mavericks (some version of 10.9.x), and assumes that you already have Mavericks installed. Won't work on an OS X 10.8.5 system, for example.
    If your MBPro is NOT running Mavericks, you have to update to that through the App Store, which will naturally give you the most recent version - 10.9.4 complete system, which would not need a system updater today. Just the security and app updates that you would normally get, too.
