Model Ambiguity?

[gkoberger]

Maybe I'm missing something, however what happens if a Schema has two fields of the same model? For example, taking the example from the main site, let's say we also want to keep track of an editor.

var mongoose = require('mongoose');
require('mongo-relation');

// UserSchema stores an Array of ObjectIds for posts
var UserSchema = new mongoose.Schema({
    posts: [mongoose.Schema.ObjectId],
    edited: [mongoose.Schema.ObjectId]
});

// PostSchema stores an ObjectId for the author
var PostSchema = new mongoose.Schema({
    title  : String
  , author : mongoose.Schema.ObjectId
  , editor : mongoose.Schema.ObjectId
});

// Attach the plugin
UserSchema.hasMany('Post', {through: 'posts'});
UserSchema.hasMany('Post', {through: 'edited'});

PostSchema.belongsTo('User', {through: 'author'});
PostSchema.belongsTo('User', {through: 'editor'});

var User = mongoose.model('User', UserSchema)
  , Post = mongoose.model('Post', PostSchema);

Am I missing something? Or can two models only be associated once?

Thanks!
