The point of some character saying that is that Higan’s mastery of multiple fighting techniques will appear in the same episode later. Otherwise those words set up expectations that would not be met.

Instead, we got a repeat of a skill he used last episode, and only one skill used, making Higan look like a one trick pony, which seems to directly contradict what was said earlier.

The writer would have been better off having ninja boss say something more general like “(Higan) was one of our strongest and most skillful ninjas”
