MAC move log confusion Cisco 9k

I am seeing some logs on our Cisco 9k that look like this:

Feb 12 09:40:08 vwn9k : 2018 Feb 12 09:39:39 CST: %L2FM-4-L2FM_MAC_MOVE2: Mac 48df.3720.9ecc in vlan 106 has moved between Po15 to Eth1/2

Po15 is the uplink port for the switch. Eth1/2 is where the device is physically connected. My question is, is this normal behavior? I know that the mac address has to be advertised on the uplink port, and it obviously will be shown on the individual interface. So is it normal to see these logs? Thanks!
