Logically, that shouldn't hold true, since the files are now scanned into the system and it's just a matter of querying the file status on GCMS system.
But then again with CIC nothing is logical :).
I'm a July 2012 transfer as well, but I confirmed my file is in London via MP, GCMS notes and an email to LVO. Best bet to really find out where your file is order GCMS notes.
