Object With Text Is Rotated. The blue box is the rotated frame around the text and the black box is the approximate bounding box of the text its a bit too big but one should get the idea. To reverse text along with the object that contains it you can do the following in Outlook Excel and PowerPoint.

However text within a flipped object is not automatically flipped with the rotation tool. I suppose it happened because of an optimization to not display invisible text. But for normal text editing happens.
Once a text is rotated you can still change its size or position using selection handles or using language commands such as OBJECT SET COORDINATES as well as all its properties.
If the object is resized in direction A its width is modified. The figure shows pieces of text with different rotation angles and different alignment options. Objects are rotated about their middle point in 180-degree increments. Note also that in order for the text objects to rotate correctly in the dimension style edit box you need to uncheck the Orient text feature.
