I think his point is probably that we aren't used to so many updates like windows users are. It IS a tad extreme. Much of this should have been addressed at the initial release of iOS 8 which was obviously rushed out.
A lot in these updates isn't about bugfixes but about new features. 8.0 had no Apple Pay, Apple Watch, etc.
What was the point of you asking what his point was, by the way?
I don't see what the frequency (or lack thereof) of updates says about anything. It certainly doesn't say much about the quality *you can bundle a bunch of fixes together in a bigger updates, or spread it out in several smaller ones, as Apple has apparently chosen to this time.
If you ask me, the big annoyance about updates on Windows isn't that they happen, or that they happen at least once a month (patchday), but that there's so much to do before and after them close apps, decide what you need to save, etc., reboot, wait, possibly reboot again, reopen apps, remember what you had open, and so forth. That isn't really the case on iOS, and since OS X Lion's Resume/Auto-Save/etc., it isn't much of a problem there either.
So, for iOS, who cares about update frequency, and why?
