Skipping Multiple var declarations in JavaScript, Bad?

I’m not sure what bugs me about writing code like the following in JavaScript

var form = button.up('form').getForm(),
    formWindow = button.up('window');

I certainly see it all the time.  Maybe I just need to get use to it.  I always right my code like the following:

var form = button.up('form').getForm();
var formWindow = button.up('window');

I understand wanting to save download bandwidth, but to me it just seems confusing to read.  Am I the only one?
