No, it's just that those "special" arguments, which may be applied to
any mapping- or abbreviation-related command, are not described there.
<expr> is mentioned with some commands (because, I suppose, it only
applies together with an {rhs}); <buffer>, which applies to all, is
listed with none.

See:
:help :map-arguments
:help :map-<buffer>
:help :abbreviate-<buffer>

'Twas the Night before Crisis

'Twas the night before crisis, and all through the house,
Not a program was working not even a browse.
The programmers were wrung out too mindless to care,
Knowing chances of cutover hadn't a prayer.
The users were nestled all snug in their beds,
While visions of inquiries danced in their heads.
When out in the lobby there arose such a clatter,
I sprang from my tube to see what was the matter.
And what to my wondering eyes should appear,
But a Super Programmer, oblivious to fear.
More rapid than eagles, his programs they came,
And he whistled and shouted and called them by name;
On Update! On Add! On Inquiry! On Delete!
On Batch Jobs! On Closing! On Functions Complete!
His eyes were glazed over, his fingers were lean,
From Weekends and nights in front of a screen.
A wink of his eye, and a twist of his head,
Soon gave me to know I had nothing to dread...
