After they've fired, they still exist and can be modified and retriggered.
See the "again" method.  You need to explicitly cancel your watchers.
Try this variant of your test program:

#! perl -w

use Event;

sub DESTROY { warn "gone $_[0]" }
sub ping {
        warn "ping $_[0]";
        $_[0]->{w}->cancel;
        undef $_[0]->{w};  # break reference loop
}

{
  my $obj={};
  bless $obj;
  $obj->{w} = Event->timer(after => 1,
               cb => sub { $obj->ping() });
}
{
  my $obj={};
  bless $obj;
  $obj->{w} = Event->timer(after => 2,
               cb => sub { $obj->ping() });
}

Event::loop();

__END__
