Is it normal that iCloud Photos on iPhone got backup on Mac when select "Download and keep originals"?

Photos has two semi-related settings here: optimize storage, and keep originals.

Optimize storage can mean some photos are cached or kept with lower resolution with the full-resolution copies in iCloud, or can be purged locally and not cached locally and (re)downloaded from iCloud Photos when the “optimized” photos are accessed, while the keep originals tries to keep the highest resolution photos on the iPhone.

Mac will backup the contents of its own photos library with its own Time Machine backups, but backups of iPhone made with macOS Finder won’t back up the iCloud Photos library contents onto the Mac as part of the iPhone backup.

I'm not quite sue what you mean by "whole photo library backup on Mac." iCloud keeps a mirror of your Photos Library-- it doesn't back it up.

Optimize works by keeping Originals and large files at iCloud while leaving only screen-sized pictures on the phone. If you as to keep your Originals locally on your phone, then it may take up 10 times as much space.

Yes, I am. This as part of a (failing?) attempt to elicit more info.

Both my Mac and iPhone are synced to iCloud Photos and I got full iCloud Photos library in my iPhone backup on Mac.

Please screenshot and post the error.

Is your iCloud subscription at its limit?

It makes my iPhone backup bigger than 100GB.

It isn’t photos using that space, if iCloud Photos is enabled everywhere.

Thanks for this link. Apparently a bug happened here. I will report this to Apple.
