This should be by design. The installer of higher prelease or patch version will replace the old one. The runtimes will only co-exist at feature band level or higher.

[Triage] @NikolaMilosavljevic please check that this reproes with newer previews. There was an issue with earlier previews on Mac OS, where new preview version would uninstall the older one.
