You have two problem:

1. To get the current value for \currentheadnumber you have use 
\determineheadnumber[section] before you use it but the example below 
shows a better method.

2. What you do with \doifelse{...}{even} is to compare the numeric value 
of the section with the string "even" which is always false. To check 
whether the value is odd or even you have to use the \ifodd command.

%%%% begin example
\startsetups [section:odd]
   \vfill
   \bold {End of odd numbered section}
\stopsetups

\startsetups [section:even]
   \vfill
   \bold {End of even numbered section}
\stopsetups

\startsetups [section:end]
   \ifodd\namedheadnumber{section}
     \directsetup{section:odd}
   \else
     \directsetup{section:even}
   \fi
\stopsetups

\setuphead
   [section]
   [aftersection=\directsetup{section:end}]

\starttext

\startsection[title=Ward]
\input ward
\stopsection

\page

\startsection[title=Knuth]
\input knuth
\stopsection

\stoptext
%%%% end example
