Why should the outlet direction of the safety valve be parallel to the main pipe axis?

Why should the outlet direction of the safety valve be parallel to the main pipe axis? I see that the specifications require this, but there’s no explanation for why; I can’t understand why such a requirement exists.
In my understanding, if the inlet and outlet of a safety valve are at right angles, with the inlet being perpendicular to the main pipe, then the outlet must be parallel to the main pipe.
If the safety valve is rotated 90 degrees, the outlet direction will be 90 degrees to the main pipe.
If the safety valve is rotated by 90 degrees, the discharge reaction force generates torque on the main pipe, which poses a safety risk.
To facilitate the discharge of liquid from the safety valve outlet
If it is not parallel to the main pipeline axis, a backward force will act on the pipeline after the safety valve activates, which could lead to more serious consequences.
Is that specified by the standard? There’s no such requirement, right? Please advise
This can be considered good engineering practice; there is no mandatory requirement
