That's one interpretation. What the rules actually say is:

(From the ARRL General Rules for Contests Under 30MHz)

   2.3.1.Multioperator, Single Transmitter: Stations are allowed only one transmitted signal at any given time.

      2.3.1.1.In those contests that do not have Single Operator Assisted class, this category includes those single operators that use any form of spotting assistance such as from nets or packet.

      2.3.1.2.Includes those that receive assistance with logging or relief operators, etc.

      2.3.1.3.Limited to 6 band changes (maximum) in any clock hour.

      2.3.1.3.1.The clock hour is from zero through 59 minutes.

      2.3.1.3.2.Band changes are defined so that, for example, a change from 20 meters to 40 meters and then back to 20 meters constitutes two band changes.

      2.3.1.4.Violation of the 6-band change rule or improper logging will result in an entry reclassification to the Multi-operator Multitransmitter class.

Ditto

My opinion: it seems the ARRL does everything they can to make the rules as obtuse and hard to interpret as possible, and spreading the contest rules across three different documents only increases the confusion.

Here's what I determine from the rules: I can host a Multi-Op Single Transmitter entry where we can run as many transmitters as I can fit in the room, as long as there is only one at a time transmitting.

While doing that, though, I've got to pay close attention to the 6-band-changes-per-clock-hour limitation, to avoid being re-categorized as Multi-Multi.

That's my interpretation. As always, YMMV.
