These are both right. Using the tail number is enough to establish radio
contact and grants permission to enter the Class C. That is exactly why
the extra "remain clear of the Class C" was included in the departure
clearance. If the tail number were not enough, then that would not be
necessary.

After departure, the tail number and a radar contact are enough radio
contact to enter the class C. If the controller needed something
different,
it would be added as a "Cessna 1234, radar contact, remain clear of the
class C."


The "remain clear of the Class C" applies only after departure and remains
in effect until overridden by an instruction that permits or requires entry.
