Not if you factor time into that math. 5x more infectious on the first cycle means just 5 times the infections, and equal hospitalizations, but the next cycle all of those 5x the number of people spread it again to 5x the number of people. So even though it's 5x milder, you've still got 5x the people showing up in the hospital. It gets worse and worse the more cycles you go. 25x in hospital, 125x in hospital, etc. You run into mitigating factors in real life, as the entire population is consumed, but that's a super steep slope comparative to the baseline.
