Unclear documentation for "ALTER ONLINE TABLE"

https://mariadb.com/kb/en/alter-table/#alter-online-table states that

ALTER ONLINE TABLE ...;
[...] This statement is equivalent to the following: ALTER TABLE ... LOCK=NONE;

and then later

This statement is equivalent to the following:
ALTER TABLE ... ALGORITHM=INPLACE;

So, is ALTER ONLINE TABLE equivalent to ALTER TABLE ... LOCK=NONE, ALGORITHM=INPLACE?

If yes, it would be great to have that as a single line on top.

Currently, it makes the impression that all three statements (ALTER ONLINE, ALGORITHM=INPLACE, LOCK=NONE) are equivalent, which I'm not sure is correct. If that's the case, stating it explicitly would also help to clarify things.
