Wooglet's Witchcap vs Zhonya's Hourglass

I actually just wanted to ask about these two items. Wooglet's Witchcap and Zhonya's Hourglass. The Wooglet's Witchcap is more expensive, which I suppose makes sense because it offers only 20ap and 5 armor less, with a passive of 25% ap boost. What troubles me is the active of both these items.

Both read:

"Champion becomes invulnerable and untargetable for 2.5 seconds, but is unable to move, attack, cast spells, or use items during this time (90 second cooldown)".

The only difference is that the Witchcap reads "Unique Active: Blah blah blah...", while the Hourglass reads "Unique Active - Stasis: Blah blah BLAH..."

Now I do believe that unique actives can stack, yes? So I guess it doesn't reeeally matter that they are the same active with different names, but my OCD says they should have the same name in this case.

I don't know why I felt to make a post about this, but maybe someone will go in and fix that small detail.
