iExpense SYSADMIN Context Operating Units is different depending on the user logging in the SYSADMIN

We are setting iExpense in a MultiOrg environment. During setup I assigned the O.U.s for which I was going to do setup in the Context tab in the iExpense Sysadmin responsibility. 

After me another colleague did setup with the same Sysadmin responsibilities but when he logs in the Context is different (it only brings the MO:Operating Unit) instead of all the ones I assigned to the context of the responsibility when I performed setup.

Is this standard functionality. I would expect that the Context is at responsiblity level and not at user level.

Please advise.
