How can I reference distinct node outputs when multiple nodes share the 'Video link' field in n8n?

I’m building a workflow in n8n and encountered an issue with multiple nodes using the same field name, ‘Video link’. I have an on form submission trigger that outputs a field named ‘Video link’, which is processed by two separate nodes (2A and 2B) to sanitize the URL before rejoining further down the workflow.
Here’s the breakdown of the steps:
• Step/Node 1: ‘Video link’ = https://www.youtube.com/watch?v=K-cTuX_QVac&t=777s
• Step/Node 2A: ‘Video link’ = https://www.youtube.com/watch?v=K-cTuX_QVac
• Step/Node 2B: ‘Video link’ = K-cTuX_QVac
In step 3, when I try to drag in a ‘Video link’ data pill, it always inserts the expression as below regardless of whether I drag it from step/node 1, 2A, or 2B:
{{ $json['Video link'] }}
I expected the expression editor to dynamically update the data pill reference based on the node source. Is this a bug, or is there a specific order or mechanism that determines which node’s output is used? How can I explicitly reference a specific node’s output when the field names are the same?
Any guidance on resolving this or best practices for handling multiple inputs with identical names in n8n would be appreciated.

When you drop a data pill into the expression, it defaults to showing the property name (i.e. {{ $json["Video link"] }}) from the current node’s context rather than tying it explicitly to the originating node. In n8n the expression editor works on the current item available to that node. If multiple incoming nodes provide the same property name, they end up merged into one generic $json object. The “order” (i.e. which value ends up in $json) is determined by the wiring order of incoming connections (and sometimes by merge rules), not by the origin name of the property.
If you want to reference a specific node’s output explicitly you can use the $node construct. For instance, if you want the value from node “Step 2A” you’d write:
{{ $node["Step 2A"].json["Video link"] }}
This way, even though the field name is the same, you count on the node reference to disambiguate the source. The current behavior isn’t a bug but instead a design decision to keep the expression simpler; data pills use the property name from the active context, and if you need to choose a specific branch, you have to reference the node.
