That's just an opinion based on your preferred interpretation of the RWBY universe.

As for Pyrrha being vaporized; she wasn't magically vaporized by some mysterious process, she was burned alive from the inside out.

Now, on to Occam's razor; the answer which makes the least assumptions is usually correct.

Pyrrha makes no mention of unlocking someone's aura creating a permanent connection, and she did it without a second thought.

We know for a fact that the process of transferring/binding aura is a new concept and required the creation of a... less than subtle bit of technology, which they didn't even know for sure would work.

For the soul binding thing to make sense you must assume that something about the process was different; you claim that his volume of aura would mess with the process, but a 50 gallon drum of water if not inherently different from an 8 ounce glass. water is water, regardless of quantity.
