How does time continue past the point of when it was "frozen" (extremely slowed), in the Episode Timescape, since Data couldn't stop the Power Transfer?

After Data fails to stop the power transfer, Picard guides the Runabout into the path of the beam and interrupts the transfer.

...However, This seems to occur at least a few seconds after the moment time "froze."

When Data scanned the singularity in the Romulan ship, there was a self defense reflex of some kind that caused time to move forward past the point when the Enterprise exploded, and then "rewind" to the moment after Data scanned it. The only explanation I can conceive of is that a similar phenomena allowed time to proceed past the frozen moment long enough for the beam to be interrupted.

Unfortunately, even if this was the case, by the time Riker hits the floor and Crusher is shot the warp core breach is already underway, so by the time he stands up the Enterprise should be exploding.

The only explanation seems to be continuity error.

TL;DR = This is a mistake, and if events proceed the way shown on screen, the crew is too late to prevent being "frozen" and ultimately destroyed.
