Why is it written in nmap official doc that -sL does not send any packet, when it actually send them?

Sniffing with wireshark, I see a bunch of ARP and DNS requests. So why in the official doc it's written this: > The list scan is a degenerate form of host discovery that simply lists > each host of the network(s) specified, without sending any packets to > the target hosts. By default, Nmap still does reverse-DNS resolution > on the hosts to learn their names. It is often surprising how much > useful information simple hostnames give out. For example, fw.chi is > the name of one company's Chicago firewall. Nmap also reports the > total number of IP addresses at the end. The list scan is a good > sanity check to ensure that you have proper IP addresses for your > targets. If the hosts sport domain names you do not recognize, it is > worth investigating further to prevent scanning the wrong company's > network. > > Since the idea is to simply print a list of target hosts, options for higher level functionality such as port scanning, OS detection, or > host discovery cannot be combined with this. If you wish to disable > host discovery while still performing such higher level functionality, > read up on the -Pn (skip host discovery) option.
