When you specify a primary of 4 cyl it can be split into up to 4 extents. It sounds like the data set had RLSE specified. If you want a single extent for the primary you will need to specify CONTIG. I think RLSE will release unused space down to the boundary of the units you used. So, if you specified CYL the smallest space left would be 1 Cyl. If you specified TRK or a blksize, then it will release down to a TRACK boundary. ROUND changes the boundary up to CYL again.
What did you specify? Was SMS involved?
