Cognitive Dissonance in Confiscation of Property: The Dichotomy between Sec 100 (6) & S 457 CrPC

Yaar samajh nahi aaya... I'm getting my head around the difference between Sec 100(6) CrPC and S 457 CrPC, both related to the temporary or permanent removal of property as evidence... and it's still giving me jitters. Essentially, both sections allow for the confiscation of movable & immovable properties, but the language used & implications are so different. 100(6) mentions 'the police may requisition or take possession of' whereas 457 CrPC talks about 'the police may seize and detain'. Is it just a matter of semantics or is there a significant jurisprudential difference between these two provisions? Please help me understand which one can be used in specific circumstances and under what conditions.
