Exactly. More users per physical server, or fewer servers to support the same number of users (cost reduction).

Also, sometimes there is planned, periodic hardware replacement. A TS can be a single point of failure for a lot of people, unless it's part of a farm. The risk of aging hardware failing may be too great.
