There is a "Find My Mac" feature. I have it turned off. If I go to
enable it there is a warning sheet which says "Find My Mac is part of
iCloud and helps you locate, lock or erase a lost Mac".
I haven't experimented with it to see the full details, but based on how
it works for the iPhone I expect that the "Erase" will do either of two
things:
(a) If the volume is encrypted with FileVault 2, it will destroy the
master key, immediately losing access to all data on the volume.
(b) If the volume is not encrypted with FileVault 2, it will have to
erase individual files or block erase the volume. It probably tries to
delete everything, but perhaps starts with files in the home folders.
Based on the description in the article, it sounds like it was deleting
files.
I'd have expected a restart to the recovery partition so that all files
or the volume could be erased without having some locked due to being in
use.

No. The wording implies the Mac is erased.

Just turn off Find My Mac if you are concerned about losing the contents
of your Mac due to a similar hack.

An iPhone with no SIM connected to a WiFi network that has Internet
access could be remotely erased via Find My iPhone. The SIM card and
cellular connectivity just makes it far easier as it is more likely to
have Internet access.
