You just had a small mistake.
Because you defined the text as a dimension, Tableau automatically placed it on the left of the screen.
I changed it to be the label instead and aligned it to the middle, now it behaves as you intended.

Not sure but find my approach as reference below and stored in attached workbook version 10.1 located in the original thread.
What i did.
1. For each individual sheet i centered the titel
2. For each individual sheet i centered.
3. Placed a "Vertical" Object on the Dashboard.
4. Placed a "Blank" Object under the "Vertical" Object on the Dashboard.
I think the whole "Solution" is now "dynamically". Let me know
