Doesn't setting this ENV var stop loading gems from the standard location?

Nope. GEM_PATH adds entries in addition to the standard system location.

$ gem environment
  ...
  - GEM PATHS:
     - /usr/lib/ruby/gems/2.2.0
     - /home/app/.gem/ruby/2.2.0
  ...
$ export GEM_PATH=/code/vendor/bundle/ruby/2.2.0
$ gem environment
  ...
  - GEM PATHS:
     - /usr/lib/ruby/gems/2.2.0
     - /code/vendor/bundle/ruby/2.2.0
  ...
