I think it really is what it seems. I got a similar offer from Uber a few months before their IPO - level 5a position, base salary $200k, $710k shares of RSU's vesting over 4 years, and performance based bonus with a target of $25k (it's not guaranteed the bonus target will be the same every year, but this is an annual bonus not signing bonus). So total comp just over $400k. I'm sure some people are inflating values on levels.fyi and some people are probably mixing up the 4-year vesting amounts of stock with per-year comp. But this example seems legit. Salaries like this are very real (and very crazy)
