The first one gets you five lines around all of the scopes without lambdas. The second one gets you five lines around all the scopes (including those with lambdas) and then omits all of the lines with lambdas, some of which will have caused a match in the first grep, and some of which may be part of the context of matches in the first grep. You will get both contexts with no match in the middle and matches with incomplete contexts.
