I watched it again last night... I still can't work it out even after the explanation

I think my brain is seeing it upside-down, inside-out, back-to-front and in reverse

It just won't lay it out in a way I can understand - kinda like when you take a sip of water and you expected lemonade, but you can't make out what's wrong. Major meltdown moment.
Dramatic mess IS RIGHT!
- Captain Janeway tells Paris to 'alter course'
-
UNSEEN: Voyager docks with the Sphere which is still under the control of Admiral Janeway
- The Sphere emerges from the rift under fire from Starfleet ships
- Janeway orders Tuvok to fire.
-
UNSEEN: Voyager fires a torpedo.
- The torpedo streaks towards the camera and impacts the inner side of the hull...
- ...and starts destroying the sphere from the inside out.
-
UNSEEN: Voyager moves to just below the surface of the sphere, and fires one last torpedo.
- The Sphere explodes, and Voyager emerges safely into the waiting arms of the fleet.
Not sure if I can get it any clearer than that!
