Function parameters (or a closure's parameters and environment variables) are global variables in the sense that they're ‟instance-wide” (within the entire function or closure) and can be accessed in local context if not shadowed by let-bindings.
But «within an entire function or closure» isn't really instance-wide? Well neither is «within an entire buffer».
The global environment is the outermost one. A buffer's environment is not. There's only one global environment. There can be multiple buffers and multiple closures, each with its own environment. ‟Buffer-local” is a perfectly good term for buffer-locals. Calling them ‟global” would be misleading, and it's good that Emacs doesn't do that.
‟Global” is the right term for globals.
