Possible issue regarding texlive path on macOS

[leehart]

variables.sh, which is used by env.sh, install-texlive.sh and install-conda.sh, has:

if [ "$(uname)" == "Darwin" ]; then
    export PATH=${TEXDIR}/texlive/bin/x86_64-darwin:$PATH
elif [ "$(expr substr $(uname -s) 1 5)" == "Linux" ]; then
    export PATH=${TEXDIR}/texlive/bin/x86_64-linux:$PATH
fi

...but during the building of the pinned envs (https://github.com/malariagen/mgenv/blob/master/.github/workflows/conda.yml), macos-latest currently uses arm64 rather than x64 or Intel, judging from https://docs.github.com/en/actions/using-github-hosted-runners/using-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories

Does this mean that the texlive/bin/x86_64-darwin is no longer correct? How can we check this?
