If the relay reconnects，relay.subscribe executed again？

[asmcos]

If the relay reconnects, should the subscription relay.subscribe(this, this.filters) be executed again?
` this.poolMonitor = (relay: NDKRelay) => {
// check if the pool monitor is already in the relayFilters
if (this.relayFilters?.has(relay.url)) return;

        const calc = calculateRelaySetsFromFilters(this.ndk, this.filters, this.pool);

        // check if the new relay is included
        if (calc.get(relay.url)) {
            // add it to the relayFilters
            this.relayFilters?.set(relay.url, this.filters);

            // d("New relay connected -- adding to subscription", relay.url);
            relay.subscribe(this, this.filters);
        }
    };`     

Will it return directly if (this.relayFilters?.has(relay.url))?
