Nmap used to send two probes for host discovery, but now it sends four

But when the target is on the same Ethernet network, Nmap uses an ARP
ping instead.

nmap determines this automatically, correct? In other words, if I'm scanning 192.168.1.0/24, and the box itself lives at an IP contained within that subnet, it'll automatically switch itself over to ARP pinging?
