[SM] Potent Enchantments + Nature's Blade interaction - working as intended?

[xcact]

The tooltip for Potent Enchantments states: "Blade Enchantments will also deal x damage over 9 seconds when they trigger."
The tooltip for Nature's Blade states: "All your melee attacks gain a 25% chance to steal x stat points from targets within 30 feet of you for 10 seconds."

After running some tests on the target dummies in Altdorf, running PE with Nature's Blade and autoattacking a single target, Nature's Blade does indeed trigger and affect the target dummies within 30 of me, and they are debuffed with -stats, however, only the target that I am autoattacking is affected by PE, despite the effect of Nature's Blade (stat leech) having "triggered" on the targets adjacent to it. However, if Nature's Blade triggers off of an AOE skill (for example, Gusting Wind), then the targets that were hit by the AOE skill which caused Nature's Blade to trigger (for example, 2 out of a block of 4 targets) will be affected by PE despite the entire group having stats stolen.

Am I reading too much into the description on the tooltip, or is this combination not working as it should be? Given PE's role as one of SM's most important damage output skills, I think this is worth getting looked at. Thoughts?
