That's a good question. Usually when BGC IP2 is triggered by LVO, you don't receive emails with the message 'your application is awaiting a review by visa officer' from them. Because they need to start reviewing your application before putting you in Progress
.
Just a few days back I was contacted by one applicant who said that that his eligibility wasn't started and that he was getting 'awaiting a review' emails to date (last email that he received was last Thursday), and that was even after his application went in IP2 on February 28, 2018. He got his GCMS notes last week as well, and they were stating that his eligibility still not started. Literally he had no changes in his notes since he was transferred to LVO. Hope this explains my point.
