At that stage it's not a hard fork, but that doesn't mean none will follow. After SegWit2X has been activated, a hard fork will follow roughly 3 months after that (it's part of that proposal). And btw, if SegWit2X is going to activate, it will happen before the first of August, as miners want to make it happen before the UASF gets initiated. Currently miners signalling support doesn't yet have any value, but this will change as everything will start to get interesting starting Juli 21 this month.
