He's talking about a style of play. Generally, "macro" play is going to for the long-game with many bases and huge armies. He calls the opposite of this as "rush." Other synonyms for "rush" are something like "timing attack" or "all-in."
Also, I don't think "timing attack" is an appropriate synonym for "rush", since timing attacks tend to occur in the early-mid game (typically off of two bases) whereas "rushes" happen within the first few minutes of the game: 7-pool, 2-rax proxy, etc.
In that vain, "all-ins" can occur at any stage in the game (though typically when a cheesy rush or committed early mid-game timing attack occurs at a heavy expense on economy) so it's not an appropriate counter-term either.
I would argue that is the case here, though your (honestly baffling) confusion might be a reasonable point against that.
