Thanks for the question, which is something I missed in the article.

According to Guo et al. (2021) (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8050950/), aerosols also evaporate quickly, and aerosolized viral concentration decline rapidly too.

But as the other commenter (Philip George Hayward) pointed out, the duration factor is also important. After all, large droplets are only emitted when sneezing and coughing, whereas aerosols are emitted all the time. Thus, in the final analysis, there will be much much more aerosolized virus (as well as virus dose or concentration) floating in indoor, poorly ventilated air than close-contact droplets.
