can any on explain what this phenomenon actually is and why its better
than forward ray tracing.

In analyzing and designing an optical system one should always (if
possible) trace rays towards the short conjugate. This gives better
accuracy in the calculations. (This is easily seen in Zemax which
seems very prone to giving inaccurate answers.)
