To ensure I've understood your query correctly, let's consider a scenario where a sine wave block is linked to a "Goto" block, with the connecting signal named "sine". When a "From" block is then connected to a "Scope", you observe that the signal name "sine" doesn't automatically appear on the connection leading to the "Scope". As a result, you find yourself manually renaming it to "sine" for the scope to display the name in its output.
To clarify, the signal from the "From" block to the "Scope" should indeed inherit the name "sine", though this name may not be visually indicated on the connecting signal. This can be confirmed by altering the icon display settings of the "Goto" and "From" blocks to show the signal name or by running the model and noting that the scope's legend reflects the signal name "sine".
