Whats the reason to pack these values?

None really, we could use 2 int64 or 2 int32. The code was just available and I copy pasted.
Do you prefer to change it ?

If we're using it elsewhere then I'm happy to continue using it. If this is the first usage I'm less inclined to introduce this as a way of storing multiple values unless there is a good reason (maybe due to perf, storage concerns etc.)
