In theory both commands should draw the same size square since the absolute
coordinates are identical, placed logically
in the middle of the ``(pstverb) (pstVerb)'' text. However, what in fact we get is a large yellow square
in the middle of this paragraph, a small, red one at the top left of this example page, and the
``(pstverb) (pstVerb)'' text output concatenated at the current text position. Furthermore, after the
red square is drawn, the font is set to red (1 0 0) -- only a \black\verb+\black+ switches this back.
The fact that the two squares are different sizes is in fact not a difference in the commands themselves
but with the \verb+dvips+ programme -- it does not reset all values correctly.
