Thanks Ramos, your nice demonstration, proves that a topological correlation, is not only an exclusive privilege of TIB knots, it may also employ and some non-TIB profiles.
In decoding your movement, and if i was to provide a guideline about this transformation, i would summarize as follows :
1. Transform the bowline into its snap/rapid/marlin spike form.
2. Pull the on going eye leg to get the Cossak.
I assume that with the term Cossak, you mean the non-slipped form of Kalmyk.
I think that the anti-bowline also plays into this field, which is a Cossack with a twisted returning bight.
