public key – Why listdescriptors yields completely different xpub keys for a model new pockets in bitcoin core

I seen that if I listdescriptors true instantly after making a model new pockets, it will listing 8 descriptors that each one use the identical xprv key.

Nevertheless, listdescriptors false would listing 8 xpub keys, and they aren’t all the identical key. Notice within the instance under how public keys begin with:

• xpub6ChP1W
• xpub6CyAaD
• xpub6Cc74F
• xpub6BmTmL

Why are they completely different?

Instance

Backing Up Descriptors

My perceive was that having saved the xprv key solely, I might have the ability to totally recreate the same pockets on a distinct node – as a result of I might derive xpub from xprv. However now I received confused – how would I derive these xpubs, and why there are multiple.
