'precariously balanced title finally is between' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'same three sides' is the wordplay.

'same' could be 'one' (similar in meaning) and 'one' is found in the answer.
This explanation may well be incorrect...

'the' acts as a link.
