Yes, I believe it works that way. If you have one at the global root, then it would be your last resort. Any ruby executable that does not specifically mark a particular ruby version using a "shebang" will run the local environment's idea of what constitutes ruby. Part of that comes from your path, but rbenv also hijacks that by creating shims to particular versions and rotating them in based on the lookup of the local version variable. I use rbenv at work, but I have much more experience with rvm, and still prefer it. That's a much larger hammer, as it hooks all shell commands to use your preferred ruby, and doesn't just shim the ruby command itself.
