that’s wrong. the device exposed the real mac address on port 5353 (udp) which is apple’s “bonjour” service, which acts as a service discovery/zeroconf network tool.
that means that other devices in the same network can know your real mac address, this makes it very easy for say ISPs to track you across networks if you use friends networks, open wifi networks in coffee shops etc.

Still within a subnet. If you connect to an internet cafe Wifi, you should be more worried about your dns traffic for identifying you.
DNS tracking can be mitigated with Oblivious DoH, DNSCrypt or even a VPN.
