Rollback-sql does not show the actual sql that will be excuted

Hello Fellow Developers,

I am trying implement rollback using Liquibase
and what I observed is that when is use the rollback-sql command I do not see the actual rollback sql in my logs.
It just shows me the version etc.
Than I looked at the specification page: rollback-sql

and even here if you expand the output section example, there are no sql statement.

Is this expected as it defeats the purpose of using rollback-sql ?
