It's highly likely that it will simply use its only interface as

That's not generally how IPv4 works. In the simple, most common
configuration, a device has an address and a netmask. For a device that
defaults to 1.1.1.1, that's probably either /8 or /24. In that case,
the device will be able to respond to addresses prefixed with 1.anything
or 1.1.1.anything, respectively.
It's technically possible that the device could have a 0.0.0.0/0 direct
route on its network interface, but it's extremely unlikely. I've never
seen a device configured that way by default. (Such a device would try
to resolve all addresses via ARP.) If a device were configured that
way, users probably wouldn't be instructed to use 1.1.1.2 as their own
address, as Bob was. And that's really the point: Bob stated the
requirement that he use 1.1.1.2 as his address, and adding a direct
route doesn't accomplish that.
