Just to clarify a bit further, in the case of the CQWW SSB and CW contests
that KR2Q was discussing, the allowance for a second station that can work
multipliers-only is unique. This rule allows for two stations to be active
at the same time, but the second one is restricted to working only new
multipliers. ARRL contests, in contrast, do not allow for a second
multiplier station in multi-single.
David's understanding is correct of the point of there being two timers. The
two stations each have their own independent 10 minute timers. This means
that your main station (that is working anyone - multipliers or not) has to
remain on a band for at least 10 minutes before changing to another band.
The multiplier-only station also has to remain on whatever band it is on for
10 minutes also.
See KR2Q's original message below for more detail about how the independent
10 minute timers work.

David,
Without a time-limit or a band-change restriction, it would be
effectively impossible for a log checker to distinguish between a
multi-single and a multi-multi station. The station could operate
multi-multi, submit their log as multi-single, and if questioned
by the log checkers argue that their one radio (ahem) just changes
bands really, really quickly.
The rule is to make sure that real multi-single stations are
not having to compete against stations that are behaving like
multi-multi stations.
