That makes sense indeed. It's more of juniors or middle programmers who usually underestimate. And the poor folks end up working nights and weekends to try to meet that estimation. But it's not that they will have more respect, recognition or salary raise if they work more than they would sign for. If I were a tech or people manager I wouldn't expect my team to overwork, just do a decent job in a decent amount of time, i.e. no slacking. And our current people manager which used to be a programmer does that. When he feels a task is underestimated he asks to raise the estimation. And the PO and the scrum master comply even if they don't like it.
