Is it necessary for a developer to have a full and a demo version of their product in market?

 
Is it necessary for a developer to have a full and a demo version of their product in market? Iv'e noticed some people add a full version and a demo version of the same at market. I thought market already has a feature for downloading demo from the full product automatically.

It's not mandatory. It's a commercial good practice.

But metaquotes already allows people to download demo from the full product so why again upload demo as a separate product?
