Index space not freed when rows deleted?

I'm puzzled.
We had a table that hit maximum extents on our QA server (unlike production it isn't cleaned out on a daily basis). I deleted most of the rows, leaving only a few thousand.
The next day, when inserting more rows I hit the maxextents exceeded error on an index on that table (of course the number of extents hadn't been reduced but I would have thought there'd be plenty of room in 121 existing extents after most of the rows were deleted). I rebuilt the index and it went from 121 extents to 1 extent, resolving the problem, but leaving some curiosity.
It's a primary key sequence based index. Any ideas?
