this version uses the LaTeX definition  \def\end#1{..}
and its behaviour is different from the pst-tree own one

\def\endpsTree{\pst at endlongbox\ignorespaces}

which you use with your second example. The LaTeX
one has a space between the two \end{..} and the pst-tree
one not. 

    \end{psTree}%
  \end{psTree}  


as you already mentioned, a % will eat the space.
I do not really know which one is correct ...
