The tell here is that you used a hyphen, not an em-dash.
Okay, see, that's context even I forget, but you're right and bears repeating:
This `-` is a hyphen, which I love, even if I'm fairly sure I'm not using it correctly in grammar a lot of the time.
This `--` is an EM-Dash, apparently, which is also what I never use but I also thought was just a hyphen in a different context (incorrect!).
