Torque converter lock-up?

I can't figure this out, any leads?
On the 2006 U151E (3.3), the converter locks when certain conditions are met: throttle opening, engine temp, Mph, load etc. (and unlocks when any fall out).
However: a Toyota mechanic told me that with the cruise control engaged the converter remains locked even if you hit "+" to increase speed slightly, and this is done to maximize mileage in cruise.
By comparison, if you try to maintain speed manually, you'll drop out of lock-up if you use too much gas, go up a slight hill, etc.
True or false?
