Your definition of macro is a lot more encompassing than how I see it used in SC2. It normally refers to just spending resources properly (constantly producing units and workers, setting up infrastructure, etc).
But if someone was microing a battle and as a result didn't look at the minimap and see a drop arriving at their base, I can totally see concluding that this player is bad at macro as a result -- macro is referring to there being a macro cycle of tasks you have to perform all the time whether you want to or not, and non-production tasks like checking the minimap and sending in a scout seem like good examples of those tasks too.
Execution of the answers to those thoughts is in the form of tactics and micro, the other two aspects of macro. If you're following current SC2 pro meta, a "strong macro player" however has more right answers to most of those questions (Stats, Innovation) and that's their strength, versus a "strong tactical player" (TY, sOs) or a "strong micro-based player" (ByuN, herO).
That said, in high-level play, "better macro" usually refers to the other things, not just mechanically hitting stride with production, as most players in the top .01% are on the same level with those mechanics.
