Two simulations (labels shown in the inset; also in Table 3) conducted to investigate counterexample morphologies. The “HeavyJ_maj5” simulation demonstrates a case where a jet propagating along the host’s major axis fails to produce prominent wings or secondary lobes (1.6 Myr), while “HeavyJ_min85 illustrates a jet launched along the minor axis (of the host) that becomes rapidly hindered, leading to decollimation and the formation of a lobe-like structure (1.7 Myr). The ambient medium’s shape is outlined with white density contour (with inline values in amu/cc), while internal contours–derived from the jet tracer–highlight the jet spine and backflowing structures for clarity.
