Difference between WAN IP Address and WAN Static IP Address?

when i look at my cable modem status page i see the below image. some octets X'ed for privacy.

why is the modem assigned 2 separate ip's? one is my static addr (173.) and other (73.) some random wan address.

i know i can remotely access the modem using the 73. wan address, but why is that even needed? why not just use the static ip 173. as the modem address with some random port, like 8800 for remote access? is it just to give the modem a separate dedicated ip in case someone uses the bridge mode? 

 

just curious about the dual ip / network setup.

thanks for the reply but this particular question isn't about an issue, just an inquiry to understand the need for dual ip addresses from different subnets in cable modems/gateways. that's all, no rush.
