Verification

• I ran brew update twice and am still able to reproduce my issue.
• My "brew doctor output" above says Your system is ready to brew or a definitely unrelated Tier message.
• This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.

What did you expect to happen?

The output of both of these commands would be empty, because all of these casks are auto_updates true, and should be excluded per the FAQ as I have the following set:

$ echo $HOMEBREW_NO_UPGRADE_AUTO_UPDATES_CASKS
1

And this is not set:

$ echo $HOMEBREW_UPGRADE_GREEDY

This was previously reported in #21972 and supposedly fixed for outdated in #21976 but it seems to have regressed since then

Step-by-step reproduction instructions (running brew commands)

Provided in the "what happened" section

[swrobel]

This still doesn't work unless I explicitly specify HOMEBREW_NO_UPGRADE_AUTO_UPDATES_CASKS when running the command. If it's set on my ENV, it doesn't seem to have any effect.

$ echo $HOMEBREW_NO_UPGRADE_AUTO_UPDATES_CASKS
