There is the same effect on the real piano that you can capture in this video 0:40

I can guess it derives from the heavy string that continues to vibrate after the damper touches it

You answered yourself.
Bass strings are longer and thicker, so when they are set in motion by the keys with a good amount of energy, the damper cannot fully stop the vibration of the entire string which requires a while to return to its normal state; just like in a guitar damping the highs it's easy, the bass even if stopped or damped has already transmitted its energy to the resonating board hence the typical release sound.
In Pianoteq you can can control this release with the damping duration both globally and per note. A key parameter when you don't want a perfectly regulated piano IMHO.

I think it's a bit of psycholoogic effect, due the contrast between the atack and the damper effect, in stacatto, compared to a longer piano key hit.
In the stacatto you have the attack and then fast the damper effect reduces it, but not compeltely for a instant, and then you have the remaining sound for almost a 1/2 second, for the bass strings in FF or FFF. For other side in a non stacatto such contrast it's much shorter, making you not pay attention in the difference of the atack to the remaining sound, since the decay it's smoother.

I tried some stacatto FFF and non stacatto FFF in pianoteq, in the first D bass key, couple minutes ago, and I got that feeling.

We can presume it can vary from a piano to another, not just due string size but also due the quality/characteristic of the damper, and perhaps even the lenght of the damper.

---EDITED--- |Such adjust already exist as the Damping Duration control, as Chopin87 mentioned bellow. See at the ACTION section. I forgot about, since I remambered about damper position and last damper, and let scape Damping Duration. há háa... shame on me.
