Yes, this is intended.  It will automatically select the source chroot
for you.  Note that in new schroot releases, the chroot is actually
named "chroot:unstable-amd64" and the source chroot
"source:unstable-amd64".  The "-source" suffix is still avilable (as
an alias) for compatibility, but sbuild uses the new names.  Basically,
it's just prefixing the names with the appropriate namespace for you,
and for the sbuild-* commands, it defaults to using the source
namespace.  You do, however, have the option of using the complete
namespace-qualified name to use a specific chroot.

You should find that
"schroot -c source:unstable-amd64" and "schroot -c chroot:unstable-amd64"
are directly equivalent.  The -source suffix will be dropped post-squeeze
once all the tools are updated to use namespaces.  Note that the
namespaces are mostly optional--schroot will by default search in the
appropriate namespace for the action you want to perform.
