This really feels like the sort of senior manager who would say "oh, this/these team/s screwed up, so here's the plan they came up with", talking about their team/s.

Speaking as a C-suite guy, "they" is about as contrary as I can think of what I expect a leader to do: it's "we", and your job is to take responsibility, both in the problems (big problems need to be explained all the way up and sometimes externally) and in the solutions (which to be comfortable with, you obviously need a sufficiently thorough understanding of the problem).

Because up the chain, I will take responsibility for it.
