Actually no: what geometry does is change the (logical) paper  
margins. The fact is that on an A4 sheet, article uses rather large  
margins. So in any case the ``there!'' are truly placed at the right  
margin. What you may want to do is add a \hbox{} after the hfill so  
that the skip (hfill) is not gobbled (unskipped) when the line is cut.

Actually what happens (more or less) is that when TeX cuts a line it  
kills any white space (stretchable or no) at the end of the line. If  
this line is the last line of a paragraph, it adds the glue  
(stretchable space) defined in \parfillskip, which here is equivalent  
to a \hfil (one l, infinitely less springy than a \hfill) So you end  
up with single line paragraphs of the form:

<left margin> \hfill Hi \hfill There! \hfil <right margin>

The \hfil being weak, it will be smashed by the \hfills therefore  
giving the impression of:

<left margin> \hfill Hi \hfill There! <right margin>

Try this:

\newcommand{\filltwo}[2]{\par\hfill #1 \hfill {#2} \hfill\hbox{}}
     \item In list:\par
     \hfill Hi \hfill there! \hfill\hbox{}
     \item Also in list:
   %Another way would be to use hfil
   \par\hfil Hi \hfil there!\par % notice, no tailing \hfil, it is  
added by \parfillskip...

Another way would be to use boxes such as :

\hbox to 10cm{\hfill Hi \hfill There! \hfill}
