Because it’s hard or often even impossible to demote someone. Compensation/title change has only one way (up) so it makes sense to give more responsibilities first to try it out and if it doesn’t work out (on either side) then the employee can go back to their previous position without any loss of face. Although I do think that 6 months is too long, a trial period of 30 days seems more fair to me.
