No it means he recognizes a life or death situation when he sees one, Magellan was one, BM was one, and so was Akainu.
But if they have to fight he will do and say the same thing to Akainu.
BM was unfortunately dealing with the MCs in an arc they were meant to prove themselves in and beat Emperors, Akainu had the luxury of being introduced in an arc where the MC was barely relevant and his story was done when Jimbei was escaping with him. Lets see how Jimbe and co react when the plan is to take down marines and an admiral. Then you can compare.
