I built a model of parallel manipulators using simMechanics, but I found that the angular velocities of the moving platform measured by bushing joint and transform sensor are different, so why?

In the given plot, I would like to know which plot corresponds to bushing joint and transform sensor. Also, would like to know how the angular velocity is measured. Is it the magnitude of angular velocity or the angular velocity in a particular direction?

Bushing joint seems to be using Euler parametrization(refer to the Joint Transformation Sequence). https://www.mathworks.com/help/physmod/sm/ref/bushingjoint.html
Bushing Joint angular velocities would be about inermediate axes. Tranform Sensor values would be components of Omega in base/follower XYZ.
