Unable to update a SketchText entity's "backwards" property

I have the following code to dynamically change the text within a sketch based on a spreadsheet value. This spreadsheet also drives whether that text should read forward or backwards. The SetTextFormat calls seem to do something -- you can see the text go from dark blue to light blue -- but the direction doesn't change. I've confirmed that the Backwards property has an initial value of False, so setting it to True should do the correct thing; nonetheless, I did try setting it to False instead, and that didn't have any effect either.

What's also very strange is that when I record a macro of me changing the text direction within the GUI, the saved macro completely lacks any steps for that action...

If it's any help, this text is an extruded boss.

Thanks in advance for any insights you may have!

    textSegments = swSketch.GetSketchTextSegments

   

    textSegments(0).Text = inpOrder.EmbossedTxt

    textSegments(1).Text = inpOrder.Id

   

    If (inpOrder.Side = Left) Then

        Dim txtFormat As SldWorks.textFormat

       

        Set txtFormat = textSegments(0).GetTextFormat()

        txtFormat.BackWards = True

        textSegments(0).SetTextFormat False, txtFormat

   

        Set txtFormat = textSegments(1).GetTextFormat()

        txtFormat.BackWards = True

        textSegments(1).SetTextFormat False, txtFormat

    End If

   

    'Save the sketch
