Unexpected CALL function with redirection

Question

I had a problem with the script, so I went to ss64.com , as usual, to find out what jewelry I can find to help me.

While viewing the page the CALL command I came across this line:

Redirection with and | <> also does not work properly.

However, this page and almost anywhere else that I looked at do not explain how this works unexpectedly. I know that I |can do some unexpected things at all , but I do not know others.

What is this unexpected feature? It depends on how you use the CALL command (calling the label vs script)?
