Your "git igv" is an alias to a shell command.

You're working on subdirectory of git worktree.

In git-config(1), we've noted that:
Note that
shell commands will be executed from the top-level directory of a
repository, which may not necessarily be the current directory.
GIT_PREFIX is set as returned by running git rev-parse
--show-prefix from the original current directory. See git-rev-
parse(1).Which is the parent directory of your "$PWD".
So, two below commands are equivalent:
$ git igv sml-binary/*
$ (cd .. && git check-ignore --verbose sml-binary/myprog sml-binary/myprog.amd64-darwin <and other files>)
From Git 2.23.0, Git allows recursive alias expansion:
igv = ig --verbose
