The '*last' mode is enabled when context needs the maximal number of 
runs for your document.


\definetwopasslist{last}
\starttext
\gettwopassdata{last}
\iftwopassdatafound
  \savetwopassdata{last}{1}{\number\numexpr\twopassdata+1\relax}
\else
  \savetwopassdata{last}{1}{1}
\fi
\doifnotmode{*last}{not }the last run
\stoptext

Hm.
From core-sys.mkiv:

\appendtoks
\ifcase\@@svn
%% 0 : unknown
\or
\setsystemmode\v!first   % 1 : first run
\or
%% 2 : successive run
\or
\setsystemmode\v!first   % 3 : first and only run
\or
\setsystemmode\v!last% 4 : (extra) last run
\fi
\to \everysetupsystem

I suppose that last=4 runs
But the max number of runs is 8 , if I've understood  mtx-context.lua
So
\starttext
%%
%% content here
%%
\startmode[LAST]\myNullMacro\stopmode%
\stoptext

# context mydocument.tex  context --mode=LAST mydocument.tex

ensure that the code inside \startmode[LAST]...\stopmode  is really seen the
last  pass

It is seen at the last run but also the first, second ... because you 
enable just a self defined mode 'LAST'.

 yes but the second context, ie
context --mode=LAST mydocument.tex
should change nothing from the first  context, so it's really the last
 (run only one time)
I mean that in
# context mydocument.tex  context mydocument.tex  context
mydocument.tex  context mydocument.tex

all but the first run exactly one time, while the first can be 5 runs and so
*last  is not the last one.

(of course one can put nasty things inside \startmode[LAST]...\stopmode etc
etc etc)

what is so important that you can include it only in the last run?

 well, in the end nothing.
I mean: nothing that I can't do with an ad-hoc  program like
MyAnalyzePdfandLog and --batch option, ie
#context --batch mydoc.tex;  MyAnalyzePdfandLog mydoc.pdf mydoc.log

why don't you use then a ctx file which process first the document and 
then MyAnalyze...

 yes I know.
The point is: while the *first mode  is clear and can be managed inside
context,
the concept of last run is problematic.
If one wants to be sure that this tex code will be parsed only at the last
run
then the tex code must be enclose inside a \startmode[LAST]\stopmode
and processed with
#context mydoc.tex  context --mode=LAST mydoc.tex
(let's forget of errors for the moment)
But   if the tex code modify  mydoc  then the first context mydoc
is superfluous.
So in the end the tex code must do nothing of relevant, and hence  it can be
replaced by an external program MyAnalyze
which in general must have as input the input source mydoc.tex, the output
file mydoc.pdf and the log mydoc.log
and processed with
#context --batch mydocument.tex ; MyAnalyze mydoc.tex mydoc.pdf mydoc.log
to take care of errors.
