But only two weapon fighting penalties, not a general 'off-hand' penalty. So it's no help if you are making a single attack with your shield. That would still suffer the -4 thanks to the glossary reference.
That lone glossary reference--not found anywhere in the SRD--makes for some shaky rules territory.
Funny how the FAQ makes no mention of handedness. In both it and the actual rules chapters, the only reference to "off-hand" is in situations involving TWF.
Seems reasonable, then, that the -4 only applies to off-hand attacks--and since the rules only mention off-hand attacks when talking about TWF, the -4 only applies in cases of TWF.
The most common method of TWF is a weapon in either hand, with the primary weapon usually held in the right hand. Which means the "off-hand" weapon--the weapon used to make the extra attack--is most commonly held in the left hand. We know that extra attack takes a -4 penalty: the TWF penalty table shows that.
Here's a situation where a constant handedness modifier (a modifier outside of TWF) would surely have been mentioned, if it existed:

Q: Can a character make a shield bash attack using the
shield as a primary weapon or can it be used only as an offhand
weapon?
A: While the rules describe a shield bash as an off-hand
weapon, that’s simply an assumption (that your primary hand is
holding a weapon). There’s nothing stopping you from
declaring your shield bash as your primary weapon. Of course,
that means that any attack you make with your other hand
becomes a secondary weapon.
A search for "handedness" in the SRD, PHB Errata, and FAQ turns up zero entries. A search for "left" turns up just a few hits, all related to "left out", or "left the area", or "points left". Handedness just doesn't exist in D&D.
You're welcome to use the glossary as a basis for a major rule impact. But be aware that -4 to all attacks made with the left hand--always, even in cases of a single attack--is a big deal, and not mentioned anywhere else in the book.
The chapters on ability scores don't mention right- or left-handed characters, or impose penalties to, say, picking a lock with the left hand or lifting a weight with the left hand. The rules for Strength mention a lower Strength bonus to "Off-hand attacks", which--when one looks up "off-hand attacks"--references only the extra attack gained when TWFing.
Shaky territory to claim that left-hand attacks always get a penalty, even when making just a single attack.
Me, I need to see rules in the SRD or in the chapters of the rulebook. Not just an appendix.
