Global placeholders don't seem to require $loop

As Detlev demonstrates here Export config - %age time contrary to Help, global placeholders do not require a preceeding $loop-$loopend.

Since this is useful behaviour, if it is defined behaviour, could the Help be adjusted to make it official?

Also, Help's statement

is not true inside a loop, as confirmed by Florian at [X] %_total_files% fails , so it would be good for the Help to be corrected here.
