Villas, I can see your contribution but don't agree with your reason that Airbus does this to smooth things out. We can and DO do that ourselves by adjusting the speed. I reckon this is a glitch that has something to do with me being in HDG mode. Just spoke to another colleague flying the same aircraft today, he didn't experience anything of the sort.
On the Boeing, we have FLCH mode. Same concept. Works as anticipated. Full climb thrust, Idle to descend. No chasing the speed.
This is the way the system is designed and works. However as I said if thrust is locked in THR CLB only way for the mode reduce speed is by pitching and there's a limit on pitch up attitude also it only pitches at 1.1 g. It has nothing to do with heading mode. You will only experience this if you reduce speed and the N1 is less than the required to switch to real OP CLB mode. Next time try after thrust is set.
