GOOG vests monthly, but if you're going to receive less than 1 share that month, then I guess they might round that down to 0 and effectively vest less frequently.
Year 1: At Netflix you get 400k in cash, you buy 200k of FB stock, so you have 200k cash, 200k worth of FB stock At FB you get 200k of cash and 200K worth of stock
Year 2 - FB stock goes up by 10% so 200k of FB stock from last year is now worth 220k: At Netflix you got another 400k in cash and you will buy another 200k worth of FB stock. So now you have 400k of cash and 420k worth of FB stock At FB you get 200k of cash and 220k of FB stock, so now you have 400k of cash and 440k of FB stock.
Also RSUs vests quarterly so you can (and should) sell it and invest in other things to diversify.
