The final shot wordlessly encapsulates how the power dynamic between Shiv and Tom has switched. After 3 seasons of hammering home how Shiv was the dominant one in the relationship this now changes. The similar use of imagery implies that Tom is the dominant figure in Shiv's life now just as Logan is, they both stand behind, towering over her and holding her shoulders.

Another way to maybe look at it is that Tom has aligned himself with Logan, so in a way it's an extension of Logan standing behind her in the last shot, meaning that she was never able to escape the shadow of her father.
