Blazing Salvo Split / Fork / Chain Interactions

It seems to me that the projectiles from Blazing Salvo neither split, fork nor chain on hitting enemies.
Even Path of Building claims in its Calc tab that Blazing Salvo's projectiles cannot split. Was this by chance an undocumented but intended change to this skills behavior?

Blazing Salvo projectiles can split/fork/chain, but only when they impact enemies directly, not the ground. This requires targeting behind enemies.
