Only later I catch the $wp_ffpc_backend_status.
I change the code to set the return value, in a optimistic way, it’s true if any server works.

I snippet the whole case code:

/* in case of Memcached */
		case 'memcached':
			/* Memcached class does not exist, Memcached extension is not available */
			if (!class_exists('Memcached'))
				return false;

            $wp_ffpc_backend_status = false;
            $_list = explode(',',$wp_ffpc_config['host']);

            if ( $wp_ffpc_backend == NULL )
			{
				$wp_ffpc_backend = new Memcached();
				$wp_ffpc_backend->setOption( Memcached::OPT_COMPRESSION , false );
				$wp_ffpc_backend->setOption( Memcached::OPT_BINARY_PROTOCOL , true );

				foreach($_list as $_server){
					$wp_ffpc_backend->addServer( $_server , $wp_ffpc_config['port'] );
				}

            }
            foreach($_list as $_server){
                $wp_ffpc_backend_status = $wp_ffpc_backend_status ||  array_key_exists( $_server . ':' . $wp_ffpc_config['port'] , $wp_ffpc_backend->getStats() );
            }

            break;
