Node.js Redis transaction: concurrent watch on single connection

Playing with nodejs, socket.io and redis transaction.
Wondering what would happen with this code (dummy code)

var redis = require('redis');  
var client = redis.createClient();  

...  

socket.on('setSomeKey', function() {  
    client.watch('someKey');
    client.get('someKey',function(err,replies) {  
        client.multi().set('someKey','someValue').exec();
    });
});

socket.on('setSomeStuff', function() {
    client.watch('someStuff');
    client.set('someStuff','blip');
    ...
});

Client 1 sends event 'setSomeKey':
-> redis watch someKey
-> redis get someKey and wait for reply

Client 2 sends event 'setSomeStuff'
-> redis watch someStuff
-> redis set someStuff & wait for reply

Client 1: -> receives 'someKey' and try multi..exec:
=> will the watch on 'someStuff' set by client2 impact the multi exec ?

In other words, could this happens while watching redis with MONITOR:
- watch someKey
- get someKey
- watch someStuff
- set someStuff
- multi
- exec => FAIL because of "watch someStuff" which has change between get and multi..exec executed in the callback ?
