You're correct, I 100% misread my docs. My package appears to be the same and really is quite generous (and makes me feel a bit better about sfdc, which is nice)
Overall will probably be a good change - as much as I liked our product, the sfdc transition was rough. For better or worse the layoffs don't seem to have been totally random: most of the affected folks I know had larger than normal equity packages
Affected by this, and unless I'm reading the docs wrong 5 months is a bit of a PR exaggeration. Health insurance is longer but pay and vesting end mid-March.
