Coming from the NE, you may descend to 2700' after crossing 30 NM from
UDUZI (in the Left Base Area of the TAA).

Since there seems to be some variation in the responses to your question,
here is the relevant AIM paragraph:

Pilots entering the TAA and cleared by air traffic control, are expected
to proceed directly to the IAF associated with that area of the TAA at the
altitude depicted, unless otherwise cleared by air traffic control.
Cleared
direct to an Initial Approach Fix (IAF) without a clearance for the
procedure does not authorize a pilot to descend to a lower TAA altitude.

Perhaps the controller should have said "...maintain 4000 until entering
the TAA". But I think his intent is clear. If he wanted you at 4000
until crossing UDUZI, he should have either stated that explicitly, or not
cleared you for the approach.


He doesn't say whether this is an actual clearance received or a
hypothetical scenario. The book phraseology would be, "Cleared to UDUZI,
maintain four thousand until entering the TAA, cleared RNAV runway niner
left approach." If he's already crossed the TAA boundary the clearance
would be just, "Cleared RNAV runway niner left approach."
