why does this config produce 5 jobs?

```auto
os:
  - linux
  - osx

env:
  - R_VERSION=r-base CONDA_ARCH=x86
  - R_VERSION=r-base CONDA_ARCH=x86_64
  - R_VERSION=mro-base CONDA_ARCH=x86_64

matrix:
  exclude:
    - os: osx
      env: R_VERSION=mro-base CONDA_ARCH=x86_64

```

been trying to figure this out for awhile now…

Because the `env` values are compared _exactly_.

I’ve said this explicitly (though it was **kind of** mentioned in `allowed_failures` before.)
