I’ll say this question lands squarely under “undefined behavior”. It may work right now, but I would advise you to not depend on it.
Can you describe the flow you’re thinking of where this is going to happen? I would imagine you could use PipelineExecute to run the pipeline in question and then have an AssetDelete snap after that to delete the pipeline when it is finished.
The pipeline and any static references to accounts and child pipelines are sent to the node when an execution is started on a node. We also save a copy of the pipeline so that if it is deleted or modified, we can reload the version used for the execution.
