how does the disagreement antony and octavious in act 5 scene 1 parallel another disagreement that occurred in act 5 scene 3?

Antony orders Octavius to, "lead your battle softly on / Upon the left hand of the even field" (5.1.16-17). Octavius contradicts him, and decides to march on the right hand side. Antony is annoyed by this, asking, "Why do you cross me in this exigent?" (5.1.19). Octavius replies, "I do not cross you, but I will do so" (5.1.20). In Act 5 scene 3 it is Cassius and Titinius who argue. Cassius is upset because he is afraid his men are running away from the field of battle. He tells Titinius that he personally killed his standard-bearer who was trying to run away and took up the banner himself. Titinius informs him that Brutus "gave the word too early" (5.3.5) and that his soldiers quickly started looting the enemy camp once they captured it. In the meantime, Antony's army has been able to surround Cassius.
