Surface points on the equator rotate at about 1000 mph, while, relative to the surface, clouds move at a few percent of that; at a global scale, the clouds aren't going to move that much over the course of three and a half hours. The moon is tidally locked to the earth and thus only rotates at about one revolution per month (about 27.3 days relative to the stars and about 29.5 days relative to the sun and to the DSCOVR satellite at the Earth-Sun L1 point which took these pictures); Again, rotation that slow isn't going to be obvious in a time lapse covering only three and a half hours (if I'm doing the math correctly I'd expect under 2 degrees of rotation during the period covered by this timelapse)
