The yearly TC numbers take the initial RSU grant (that vests over a 4 year period, usually with a 1-year cliff followed by monthly vesting) and divide it by 4 to get the "initial RSU grant options vesting per year". Typically you never want anyone (that you want to keep) to be fully vested, so it's expected that you'll get new grants to top up after a couple years if you're doing OK.
