That sounds a bit more calculative than my impression of it. Running around desperately trying to win the gamble was the only thing Lawrence thought he could do (as dictated by his dense personality centered on trading alone). He was afraid of losing Horo and did all he could to prevent that.

While it technically sounds like the same thing, there's a difference. It's like the difference of a man jumping between a bullet and his love interest instinctively compared to a man pondering that if he jumps between a bullet and his love interest, the woman might be thankful to him.
