In oracle's "Enterprise DBA Part 1A : Architecture and Administration" vol.1 page 1-20

The processing of a DELETE or INSERT command uses similar steps. The before-image
for a DELETE contains the column values in the deleted row, and the before-image
of an INSERT contains the row location information.

What can be called row location information ?

The ROWID psuedo-column describe the physical location / storage information related to a row.

Both DELETE and INSERT have to deal with that.

So my guess is that "row location information" mean ROWID value.
