It's not a typo.

All +Jump enhancements boost both attribs, but they don't all say that. The originals, TOs, DOs and SOs, all use the same basic nomenclature, referring to "distance" and height rather than speed and height. When IOs were added, the terminology was changed to "jumping ability". The new(ish) Launch enhancements are more precisely worded, stating that they improve speed and height.
The other one to which you referred in your first post, https://cod.uberguy.net/html/power.html?power=boosts.attuned_launch_d.attuned_launch_d , denotes "Increased Jump Height" in the name because it has a third attrib on it, +level_variable% Maximum Jump Height. It's the Launch set's special enhancement, like Hypersonic's +Fly Protection. It doesn't just boost Jump Speed and Jump Height, it boosts those and bumps up the ceiling for Jump Height. On my Staff/Willpower brute (+Movement Speed set bonuses, Combat Jumping and Athletic Run, no classic travel power), it increases Jump Height from 56.82' (without) to 69.59' (with). If I were to replace it with Springfoot: Jump/End, which has the same 26.5% boost to Jump Height but no +MaxJumpHeight, I'd top out at only 58.94'.
