I think the first sentence of the author counters your comment. What you described works best in a familiar codebase where the organizing principles have been maintained well and are familiar to the reader and the tools are just the extension of those organizing principles. Even then a deviation from those rules might produce gaps in understanding of what the codebase does.

And grep cuts right through that in a pretty universal way. What the post describes are just ways to not work against grep to optimize for something ephemeral.

Agree. Not just because it's unfamiliar code, you can also get a feel for how the program/programmer(s) structured the whole thing.
