Yes, you're right in the sense that only one request for substitution can be made, and that's by a player entering the sub zone. You're also correct in the sense that a team is allowed as many entries in the same dead ball request.

For a team to make multiple substitutions in the same dead ball, they need to be waiting outside the sub zone until the first pair is clear. In this instance, they are to be considered acknowledged under the same initial request.

15.10.14: "If a team intends to make simultaneously more than one substitution, all players being substituted must report to the substitution zone at the same time to be considered in the same request."

You're not inferring multiple requests in this instance considering their request is still being acknowledged. Just because the first sub has received authorization to enter doesn't mean their request is complete because they have another pair awaiting entry. Per 15.10.14, they're making a single request to allow multiple substitutions; when multiple pairs arrive, they are to be treated as one request. You allow their legal request (12th), but deny the 13th due to being over their maximum allowed number, thus making it an improper request.
