ID 588893 - The documentation and tooltips for the Merge node's Hardlight and Overlay operations appears to be incorrect

Problem summary
The documentation and tooltips for the Merge node's Hardlight and Overlay operations appears to be incorrect.
 
Customer reported version
N/A
 
Customer reported platform
 
Steps to reproduce
 
1) Look at the expressions listed on the Merge node's tooltips, or in the online documentation: 
https://learn.foundry.com/nuke/content/reference_guide/merge_nodes/merge.html 
 
Expected behaviour
The documentation should be correct (see comments below).
 
Actual behaviour
The documentation appears to be incorrect.
 
Workaround
Unknown.
 
Reproduced by support
This issue has been identified by our developers.

 

We should test the updated documentation in the same manner the customer did, comparing the output of Merge with expression nodes with the same expressions. The output of the Purple and Grey backdrops on this script should match.
