Captain if I am right about placebos being move to treatment before progressing, and them getting removed from placebo group, then the placebos are enriched with deaths who did not crossover. 30/99 < 30/79.

This would have a beneficial impact on the likelihood of statistical significance in the original mortality analysis.

You could also censor them at the time they crossover which still substantially hurts placebo group.
