The point is this text from the Swim skill:
You can hold your breath for a number of rounds equal to twice your Constitution score...
and
You can hold your breath for a number of rounds equal to [...] your Constitution score...
depending which printing of the Player's Handbook or which SRD you quote.
This inconsistency is adressed even by other game companies, as I was about to uncover.

Hmmm
I don't understand.
The complete text says exactly what I stated - it depends on what type of action you are performing.
SRD
SWIM (STR; ARMOR CHECK PENALTY)
Check: Make a Swim check once per round while you are in the water. Success means you may swim at up to one-half your speed (as a full-round action) or at one-quarter your speed (as a move action). If you fail by 4 or less, you make no progress through the water. If you fail by 5 or more, you go underwater.
If you are underwater, either because you failed a Swim check or because you are swimming underwater intentionally, you must hold your breath. You can hold your breath for a number of rounds equal to your Constitution score, but only if you do nothing other than take move actions or free actions. If you take a standard action or a full-round action (such as making an attack), the remainder of the duration for which you can hold your breath is reduced by 1 round. (Effectively, a character in combat can hold his or her breath only half as long as normal.) After that period of time, you must make a DC 10 Constitution check every round to continue holding your breath. Each round, the DC for that check increases by 1. If you fail the Constitution check, you begin to drown.
The DC for the Swim check depends on the water, as given on the table below.
I haven't found a version of the PHB that differs from this yet.
The amount of time you can hold your breath depends on what type of action you doing at while holding your breath.
Move and free actions = twice your Con score.
Standard and full round action = 1 round less (effectively half as long)
I am assuming we are talking about 3.5 by the way.
