Yep, your suspicion is correct.

If you have `nohidden` set, and it sounds like you do, Vim won't let
you open a new file in an existing buffer if the buffer has changes.
To avoid the annoying warning prompt in this case, both Command-T and
evidently NERDTree just open in a split instead.

Try setting `:set hidden` (see `:h 'hidden'` for more details) if you
don't like this behavior. Then Vim will allow you to move buffers with
unsaved changes out of sight without any annoying prompts. It's quite
safe to use this setting as if you try to quit Vim without those
changes being saved it will still warn you.

Cheers,
Wincent
