This is a weird comparison. On one hand you have an independent contractor preparing for an engagement. The other is actively collaborating with a team to make a thing. The less bad (but still not great) comparison is to Reeves' allocation of time during principal photography.
On multiple occasions I've spent weeks out of the office in training sessions. Even with on-site training we were pretty good at turning peoples' responsibilities off so they could maximize the time spent with someone we flew in for a few days. Or there's that big bit of training before getting a job at all: university. (That's another rabbit hole of arguing about topical focus within education, but still a portion of someone's life dedicated to learning.)
I can kinda see what the author is trying to get at, but it's weird to use training to make a point about time management. Training is the main type of work I've seen offices willing to let someone go fully incommunicado. Unless you work somewhere that doesn't believe in training. And cramming an online module in between normal tasks isn't training, it's more like reading documentation (it's a con so the personnel software can get an entry that X is trained in Foo).
