Lightroom :: White Balance Copy / Paste - Absolute Or Relative Value?

The question is basically when you copy the White Balance setting from one image and paste it into another, is the pasted setting an absolute value or a relative value?
 
For example... I import three RAW images, each shot with Auto White Balance.
 
Image #1 is a gray card and with a WB of 6500K.Image #2 is a product shot with a WB of 6000KImage #3 is a product shot with a WB of 6200K 

Let's say I adjust the WB in Image #1 to 6400K - an adjustment of -100K from the "as shot" WB.
 
When I copy those WB settings from Image #1 to Images #2 and #3, will the target images get an absolute value of 6400K? Or an adjustment of -100K?
 
Would I have:

Image #1 = 6400KImage #2 = 6400KImage #3 = 6400K 
... or ... 
Image #1 = 6400KImage #2 = 5900KImage #3 = 6100K
