I get that this appears to be the conclusion the author wants you to draw. But what's missing, to me, is that she has provided no evidence whatever to support it. The only evidence we have about her boss is his reaction--and I can see a boss with a high tolerance for risk saying exactly what she describes her boss as saying, as a kind of whimsical recognition that the very thing that makes her a valuable employee is that she will take on these things that none of his other employees will take on. So on the only evidence she gives us about her boss, it could go either way.
What I expected to see (and apparently you did too), at some point later in the article, was some kind of follow-up to that specific story she told--some way in which either her boss did or didn't support her in some subsequent development related to what she had already told. And there wasn't one.
