It really depends upon the manufacturer of the drive as it varies.  The
good manufacturers implement secure erase by simple changing the encryption
key making all the data unreadable.

There have been a few papers that talk about this but I can't find them
now.  Google Scholar turned up a few, but the ones I checked weren't
the one I was thinking of.  The ones I'm thinking of are 10+ years old,
and I don't remember seeing much recently.
