Google Index - increase in pages returned

Canonicals and www and non www

[300m]

I am a little confused by the whole process, but I was wondering something. I have seen countless posts about index results for various keywords increase, double or triple what they once were before big daddy.

If big daddy is a new infastructure and one of its primary functions is to tackle canonical, and 301's would it be fair to say that Google has increased its index size to include all of those issues?

Meaning, include the www and non www etc as individual pages, hence causing the index to increase. This way, they could have all of the problems tackled at one time, then after they have fine tuned big daddy, roll back to a more normal index size and keep big daddy fishing out the stuff it initially did not catch?

Of course I am speculating, but it could make sense, given that several people have stated that the index results have boomed on their terms.

Personally, I think this may be the case and wanted to know if anyone else has considered this to be possible.
