Because you don't call fetch() the statement handle is left as
"active". When you call prepare below DBD::Sybase opens a new
connection for you (it can't tell that there are no rows to be fetched
[well, maybe it could, but right now it doesn't]).

So what happens is that you are querying @@identity on different
connections, which will always be 1.
Try this:
$qd = $db->prepare("insert into test (blah) values ('one')\nselect
\@\@identity");
$qd->execute;
do {
while($d = $qd->fetch) {
print "Identity: $d->[0]\n";
}
} while($qd->{syb_more_results});
