In the unspecified historical Mahr example, “middle category” itself is determined by value. Even when a person from that category is delivered, value is needed to establish that category.
This is the reasoning:
• giving money instead of the person is substitute-performance, hence Qada;
• but value was already central to identifying what was due, so paying it also resembles original performance.
The resemblance does not erase the difference between delivering an individual and giving money. It explains why this Qada has an Ada-like aspect in the particular example.
