Using the excellent solution to compress citations for @set members provided by moewe in this question results in an unexpected behaviour of the compression mechanism if members of different sets are combined in one \cite command. Obviously the internal change of the @set is not reliable recognized so the macro gets confused.
In the following MWE I have implemented a check for the change of sets that can be switched on or off by \toggletrue{adapted} resp. \togglefalse{adapted} to reproduce both variations.
What I just don't get is why moewes solution does not work as expected - so basically it's more a question out of curiosity...
The result of the MWE is
where in line 3 the original code is used and in line 4 the adapted one.
