If you need to create a new field alias that would be in two sourcetypes?

I am getting conflicting information, so I just wanted to ask. If you need to create a new field alias that would be in two sourcetypes, do you need to create two different field aliases or just one.

Aliases are created to apply to a source, sourcetype or host, so if you have 2 sourcetypes, that do not have common source/host, then you will need two aliases.
