Why does the conversation between Caesar and Freeman about the Declaration of independence leave the reader with a sense of ambiguity, but hold greater significance once Freeman's identity is revealed?

Ambiguity is created due to changes in the plot.

Explanation:

Ambiguity is created due to changes in the plot. This is because although Jefferson showed interest in defending the freedom of all citizens through the Declaration of Independence and Caesar Rodney agreed with that and even signed the Declaration of Independence, he suggested that the text be changed, changing the signatories' names to protect the people who signed it. This generates a certain ambiguity, especially in relation to Rodney's real intentions.
