There is an inconsistency between the way the description of pounce is written and the way it's often used.
Examples:
Pounce (Ex)
If a tayellah leaps upon a foe during the first round of combat, it can make a full attack even if it has already taken a move action.
Pounce (Ex)
If a weretiger in tiger form charges an opponent, it can make a full attack, including two rake attacks.
Pounce (Ex)
If a dragonne charges, it can make a full attack in the same round.
Pounce (Ex)
If a deinonychus charges, it can make a full attack.
So let's see why the use of pounce of inconsistent.
First of all, for a Tayellah, pounce seems to only apply to the first round of combat while still being called pounce while the other examples seem to have the same ability that's usable with any charge.
The entries for weretiger and the dinosaur are a bit vague although it seems very reasonable to most people I know that the one attack is subsumed into the allowed full attack.
Dragonne's wording with the comma and "in the same round" seems to separate the charge into the charge and a later, same round, full attack.
Overall, the RaW evidence seems to lean slightly towards attack followed by another full attack.
Now bringing in RaI, Applying some logic, having 6 seconds to attack someone should not allow LESS attacks than running at someone for 2-3 seconds and then attacking. Sure running gives you momentum, but how can it possibly give you more attacks?
All the DMs I've had ruled with what I consider to be RaI and said that pounce only allows a single full attack at the end of the running part of the charge.
