How does resizing blocks to same size work in Simulink?

When I use Format->Resize blocks -> Resize block to same size , I am not sure what determines the size of the resultant blocks. If I have three blocks of different sizes, and resize them to same size, how does simulink decide the block whose size is taken as the reference to apply to all the other blocks ?

The block to whose size all the blocks will be resized is highlighted in white square corners as shwon in the attached figure (resize_reference.jpg). After selecting the blocks to resize you can change the default reference block by clicking on a block (that is one of selected blocks) that you want Simulink to take as reference. You can see the highlighting of white square change when you do this.
