Good explanation of a TS, slightly confused. To summarise A TS has positive second derivatives in all coordinates apart from one which is negative, the reaction coordinate (in the basis of normal modes).

Excellent understanding of TS theory

'flee from the transition state due to excess energy' - Just use the term re crossing here.

You could have given a suitable example of the reverse example and hence proved Polyanis rules.
