I have a few problems with systems whereby you subtract an amount form you're own skill to inflict the same penalty on you're opponent.
The version whereby anyone can do this any time is open to massive abuse. Even for modest differences in skill, the more skilled character can 'bury' their opponent. E.g. if I have 75% skill and my opponent has 50%, I just take a 45% penalty. I'm now rolling against 30% versus his 5%. Game essentialy over. A limitation of some kind, such as half skill, might ameliorate this but it would still introduce odd effects in combination with other mechanics in the system.
Subtract skill over 100% makes a bit more sense, but it means very highly skilled characters (say 180%) will walk all over any opponent under 100%. Well ok, maybe that's no big deal, but it does mean they will just walk streight through them without breakign step. Right now combat skills over 100% are badly treated. The only effect it has is to increase critical chance (whoopee do, +50% skill yields +5% crit chance), or provide free points for precise attacks. It's prettly clear Mongoose are saving the 'real' combat system for experienced characters for yet another supplement.
