I don't think so. From the AIM 3-2-4,
3. Arrival or Through Flight Entry Requirements. ...

NOTE-
1. If the controller responds to a radio call with, "(aircraft
callsign)
standby," radio communications have been established and the pilot can
enter
the Class C airspace.

2. If workload or traffic conditions prevent immediate provision of
Class C services, the controller will inform the pilot to remain outside
the
Class C airspace until conditions permit the services to be provided.

3. It is important to understand that if the controller responds to
the
initial radio call without using the aircraft identification, radio
communications have not been established and the pilot may not enter the
Class C airspace.

EXAMPLE-
1. [Aircraft callsign] "remain outside the Class Charlie airspace and
standby."

2. "Aircraft calling Dulles approach control, standby."


The material you quoted does not support your position.



I think that this makes it pretty clear that any acknowledgement of a
specific aircraft without a specific caution to remain clear is sufficient
radio contact to allow clearance into a Class C.


Yes, but that's not the case here. In this case there was acknowledgement
of a specific aircraft with a specific instruction to remain clear of the
Class C airspace.



Using your example of a subsequent instruction implicitly
canceling a previous instruction applies here as well.


It doesn't apply in this case because the instruction to remain clear of the
Class C airspace was the only instruction issued.
