I thought I knew the answer to your question, but wasn't sure.
Therefore, I consulted the oracle (man).

By doing "man arp" I found that arp is address resolution display and
control. An excerpt from the man page says:

The arp program displays and modifies the Internet-to-Ethernet address
translation tables used by the address resolution protocol (arp(4)).

So, I'm concluding that what you're seeing is the host updating it's
routing tables to reflect that it now knows the route to xl0 on
192.169.1.10 which is via 00:0c:6e:38:d7:d7.

I think I'm correct, but maybe someone else can back me up or point out
any errors in my assessment. The moral of the story, though, is read
the manual. It will at least give you a starting point and often times
is enough to help you get to the root of your problem without further
help. As Yoda would say, "Manual should you read. Help you it will."
