Wildshard + Additional Spell Projectiles

Not sure if intended but when taking the passive skill node Additional Spell Projectiles + Wildshard it seems that:

1.Rather than having separate instances of 1+2 projectiles & Wildshard 20% proc chance of 8 projectiles

2.Wildshard gets + 2 projectiles (i.e 10)

This has been happening on my frostbolt skill
