Is this an example of weak Ni in my ISTp husband?

He had this project he had to do this morning, and he just started up with doing step F without realizing he really should do A, B, C, D, and E first. And then when he realized he'd done things out of order, he came inside all irate and upset and said, "This is so fucking annoying! I can't do this until I do that, and I can't do this until I do that. I hate that!"

He didn't end up having to do everything over - just a little bit, but he wanted me to stay out there with him for no other apparent reason than to make sure he did everything that had to be done.
