Aloe Vera babies, repotting

Got a large wide leaf that needs repotting. It has shed bottom leaves many times creating a long “neck”, has leaned to around 45 deg.
Need to know if I should bury the neck. I figger it’ll just re-incline if I don’t.
Also need to know how to make it have "pups. YouTube videos titled how to are in foreign language.

Burying the neck may be what leads to pups. That isn’t a definitive answer, but I remember once long ago having an AV that produced a bunch of pups without my prompting, and IIRC it had a long prone stem touching the soil.
