In the Networking protocols NAT section shouldn't step 5 say "The Device" not "Host B" performs the NAT table lookup ?

Inside source address translation

5. Host B uses the inside global address as a key and performs a NAT table lookup, then translates to the inside local address of host 10.1.1.1 before forwarding the packet

Overloading of inside global addresses

5. Host B then performs a NAT table lookup, using keys as the protocol, plus the inside and outside addresses and ports. It translates to the inside local address 10.1.1.1 and forwards the packet.

Yes, you are right. 

They are referring "the device" to the blue router with the nat table. 

So yes it will be the device that will be doing the nat table lookup. 

Host B is an end device, saying, "Host B uses the inside global address as a key and performs a NAT table lookup" would be incorrect in this case.
