Not necessarily. By layer I'm guessing you mean data source? If so you can certainly have multiple MapServer layers that reference the same data source but style the data differently. You can also have a single MapServer layer that can be configured dynamically to style the data differently. For example, you might have a constant thematic presentation based on a percentage value (e.g. 0->10: green, 10-20:yellow, etc...) and then you use different attributes (e.g. % income above $50,000, % age > 60, % residents with yellow beagles) against that classification. All sorts of possibilities depending on your data.
