If more than one address is supplied, then when the client boots, it will be assigned the address that corresponds to the network on which it is booting. If none of the addresses in the fixed-address statement are valid for the network to which the client is connected, that client will not match the host declaration containing that fixed-address declaration. Each address in the fixed-address declaration should be either an IP address or a domain name that resolves to one or more IP addresses.

These are both good questions.
In my experience, one should never assume that the DHCP man pages are 100% accurate. They are not.
