In response to Smalley and Antonia's comment, we agree that our statement that closer‐to‐zero velocity–velocity‐increment correlation for larger turbulence intensity values cannot be taken as a measure of homogeneity. We also explain that, although not aware that the velocity–velocity‐increment correlation cannot be zero at finite r 1 , we concentrated most of our analysis on its tendency towards zero with decreasing r 1 , since this limit is well known for homogeneous turbulence.
