Any reduction in power would have created a significant AND moment. The longitudinal acceleration was positive throughout- right up until the final MCAS AND. (0.1g at end equivilant to 0-60mph/0-100kmh in 27seconds.) The actual acceleration provided by thrust would need to be calculated using both vertical (above 1g) and longitudinal (above 0g) acceleration data.

That thrust moment of the engines coupled with the aerodynamics of the engine cowling was in fact assisting them with pitch (and would do so with diminishing effect up until VH) The fact that it also masked the true trim when they initially cut it out is possibly the reason why they didn't attempt manual trim wheel as soon as cut outs were flicked.
