ClearAlll error message

Just out of curiosity.  The following ClearAll works as expected.

  name=Symbol["A"]; ClearAll[name];

But this elicits an error message:

  ClearAll[Symbol["A"]];

Why?  A non-standard argument evaluation?

[The message came deep from the bowels of a complicated code
to find tensor invariants. A module received a string from which to
build related symbol names with that string as root]
