The first one is intended to address the problem expressed here: https://twitter.com/AdamMc331/status/1331662669712158723?s=20

When used inside a function in a class, the live template will prefill the class and function names.

When used in a top level function, the cursor is placed so that you can type something for the class name (or not).
When used in a class, but outside a function (e.g. property assignment), the template will place the cursor so that you can type something for the function name (or not).
