This is true but there are some caveats.
The lockLoc of the second image must either be false OR the second
image must be the exact same size as the first image. Otherwise the
image/alphaData of the two images will not be the same.
Example: If the second image was twice the size of the first image
(and had lockLoc set to true) and you assigned the text of the first
image to the text of the second image then the imageData/alphaData
would NOT be the same. This is because the imageData represents what
is *visible* on the screen and the two images are not the same size.
What is most likely happening under the hood is that when you assign
the text property of an image control Rev is creating the image/
alphaData based on the current size of the image control.
