Usage of "adequacy_model" in the `def _active_to_passive()` and `def _passive_to_active()`

[SuperBruceJia]

In the codes, an adequacy model is applied to score and rank the generated sentences. (1) def _formal_to_casual(): https://github.com/PrithivirajDamodaran/Styleformer/blob/main/styleformer/styleformer.py#L69-L95 (2) def _casual_to_formal(): https://github.com/PrithivirajDamodaran/Styleformer/blob/main/styleformer/styleformer.py#L97-L123

May I know why it is not used in the def _active_to_passive() and def _passive_to_active()?

Thank you very much!
