No, it says more. In particular:
If you specify a larger value, garbage collection will
happen less often. This reduces the amount of time spent garbage
collecting, but increases total memory use. You may want to do
this when running a program that creates lots of Lisp data.
However, we recommend against increasing the threshold for
prolonged periods of time, and advise that you never set it higher
than needed for the program to run in reasonable time. Using
thresholds higher than necessary could potentially cause
system-wide memory pressure, and should therefore be avoided.

Again, you are reasoning about the value as if it were related to the
maximum memory footprint Emacs could have. But in fact, it is related
only to the _increment_ of memory Emacs can have before it should stop
and consider how much of that is garbage.
