The matches may be held at the same ground. But there is a chance that different set of pitches are used for them. As far as I know, most of the grounds have 2-3 pitches and the curator usually prepare 1-2 additional pitches in addition to the main one. If that is the case, then the concern about the surface deterioration doesn't make any sense.
@JSRAW in my personal opinion no player will try and harm the pitch because if he’s found guiltily of harming the pitch then he would be suspended for few matches, and it would even tarnish his image. Also I believe that ICC would have thought this through and they would be regularly inspecting the pitches, and in any case if a pitch is found unplayable then I’m sure that they’ll request ECB to immediately change the venue.
