I would suggest making the data set and running the code to see the results.

Work.one gets 3 records from the first conditional Output.

Then OUTPUT writes records to both output sets unconditionally, so that is 5 records written to both.

Result: 8 records.

Because there are two outputs in the program. The first one will output var1=a in dataset ONE. The second one will output all presented observations in both datasets. So there will be 8 (3+5) obs in summary.
