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.
188.8.131.52.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.
184.108.40.206.Includes those that receive assistance with logging or relief
220.127.116.11.Limited to 6 band changes (maximum) in any clock hour.
18.104.22.168.1.The clock hour is from zero through 59 minutes.
22.214.171.124.2.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.
126.96.36.199.Violation of the 6-band change rule or improper logging will
result in an entry reclassification to the Multi-operator Multitransmitter

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
That's my interpretation. As always, YMMV.
