I'm not an authority on this, but I think there is only one missing piece
to your understanding. In the broadcast TV world, the beginning of a
program, that is, what I would think of as zero hours, zero minutes,
seconds and frames, is defined as one hour (01:00:00:00) on the time code.
I've been told that this was done to be able to queue in items before the
start of a show, such as commercials, promos, announcements, station
identification, etc., without needing negative timing numbers. That time
code convention has become more generalized than just broadcast TV, but it
doesn't show up everywhere. The inconsistency makes it even more
confusing.

So I would read your time code example as "one hour" which is really zero
hours, "zero minutes," "eleven seconds," and "twenty-four frames."
Basically, just as you predicted, except for the artificial hour figure.
It's kind of like daylight saving time...
