Yes, there is no need for it. That's why in Linux SEXTANTE assumes
SAGA is on the PATH and doesn't let you the folder yourself manually.

There is a default for GRASS because SAGA is bundled with QGIS. For
the other ones, they could be anywhere in the system. Now that they
are going to be installed along with QGIS by the OSGeo4W installer, I
will add default paths for them as well.
