Location for oil holes on rocker arms?

As you can see, the hole on the underside is offset to the side.
So it likely does not intersect the space between the bushings.
If that’s how it is, and the oil has to squeeze between the bushing and the shaft to get into the hole, then they’re employing that clearance as a way to meter the oil out to the valve.
To me, if that’s how it actually is....... I like it.
With the engine running and warmed up you would get oil coming out of the hole...... but very little while priming the engine.

That’s a similar situation as to how solid roller lifters meter the oil to the top for pushrod oiling.
