Yes, internal resistance is via the balance port.
And all LiPo battery chargers behave this way. Lithium Ion as well. Charging starts to slow down over 80%. Even if you aren't balance charging.
From what I know, there are two reasons. One is heat management, the other is as someone else mentioned - so it doesn't over shoot the charge target.
Think of it like pouring water into a glass. You start slowing down toward the top so you don't spill.
Balance charging can definitely take some additional time. But I absolutely agree with Liberty, if you are seeing extended balance times you should check your internal resistance. What i'm seeing in that picture looks high.
