When SAS sees the DESTINATION for the first time i.e. ‘London’ it sets the length to 6 characters…Therefore the value ‘Copenh’ is assigned to DESTINATION becoz of the length.

I think Memory is allocated for variables before the data steps are executed. During this pass sas looks for the statements that first initialize the variables. At this time memory is allocated depending on the length of the value being assigned to it. Later this memory length does not change for character variables. Additional memory is not allocated to the variable as the length of character variable increases. there is no dynamic memory allocation.
