from the top to bottom:
>80% is supporting
Soft fork during the 21-29 with signalling for BIP91
if it locks in until tomorrow then there is no NO part (if it didn't i will add more information here tomorrow) because so far we are above 80%
when Yes part happens, SegWit is activated with majority. if by the deadline (Aug 1) there is anyone left who has not upgraded to SegWit, their blocks will be rejected by the majority (orphaned)
after SegWit BTC (that circle in the end) is MOON

we have some more stuff coming on Aug 1 like Bitmain wanting to individually split from the rest of the network, but since nobody wants or supports it, i call it a dumb move and may not even happen since their purpose was to go against UASF and with the current trend there is not going to be any UASF.
the next step is the 2 MB hard fork somewhere down the line, which we can't say what will happen at this point. lets get SegWit activated for now and get it working for a couple of months first then worry about that.
the bottom part of the chart is not going to happen as i explained above and if things change i will post a new comment tomorrow...
