If I read him correctly, he is saying that only 30 per cent of current employees will be there in a year. It is possible that some of them will be replaced by other people who now work elsewhere and who will try their luck with remodeled Twitter. There will likely be a major cultural shift at Twitter; for someone, deeply repulsive, for other people, possibly very attractive. So there might be significant staff churn even though the total numbers may stay similar.
