VMware workstation Pro :- Guest OS ( configured in Bridged mode ) mac address doubts ?

Hey all, this might be a noob question, i apologize in advance. I tried searching on the internet, but couldn't get any answers.

So i'm running Kali ( guest OS ) in workstation pro. My host OS is windows 10. Guest OS is configured in Bridged networking mode.

Consider the following parameters of :-

1. Guest OS - IP_G:MAC_G
2. Host OS - IP_H:MAC_H

ARP table of :-

1. Guest OS - IP_H:MAC_H ( perfect )
2. Host OS - IP_G:MAC_G ( perfect )
3. Another Host ( within the same network as Host OS ) - IP_H:MAC_H ( perfect ) , IP_G:MAC_H ( why? )

why does another host have the mac address associated to IP_G as MAC_H ? shouldn't it be MAC_G?

Also My guest OS doesn't show up in the router's connected devices, is it because the Guest OS didn't actually authenticate and associate with the router as explained in this post? or is there any other reason?
