There's also:
Global variables must only contain invariant values
(see~\ref{sec:metadata-invariance}). If a global variable's value is
invariant, it may have the value that would be generated at any
given point in the build sequence.
which is true for all global variables, not just for metadata ones.
That paragraph's there because historically global variables have done
various different things (being re-evaluated for every phase, or just
some phases, or never, or when loaded from VDB, or ...).
