Odds are, that top of the blue portal is really near the shorter edge of that rectangular block. Walk up to it. When you get really close, you will get "sucked in". You will have visibility as if you were in the orange portal, and you can shoot. Shoot the ceiling, and you (and the cubes) are upside down without falling, etc. But. . .walk away from the portal edge, and you are back on the ground again.

I was getting some similar behavior on one of my maps. I have a couple 128x128x8 platforms and I've noticed myself getting caught in them in strange ways and even somehow lodging myself inside the portal while still being in the solid part of the block. I think it's pretty clear that while the portals are displayed as ovals, the actual collision hole is more rectangular in shape.

The two-cube thing sounds pretty cool though. Making a platforming puzzle could be neat, but once somebody does it I'm certain it will get old fairly quickly.
