Puzzle From A Math Teacher - If AAA + BBB + CCC = BAAC, What Are A, B, C = ?

The solution seemed a bit too complicated to me. My take which I think is a bit easier...

 AAA

 BBB
 CCC

----

BAAC

1. Given base 10, looking at the digits column, A+B=10 (2 digits cannot add to 20)

2. Since we carry a 1 to the 10s column, C+1=A (Cannot carry a 2, see above)

3. Since, A+B+C results in carrying a 1, looking at the thousands column, B=1.

Putting B=1 into 1. above gives A=9 (from A+1=10)

Putting A=9 into 2. above gives C=8 (from C+1=9)

We now have A=9,B=1,C=8 or:

 999

 111
 888

----

1998

Is there a flaw in this reasoning chain?

Consider this wrinkle:

 BCA

 CAB
 ABC

----

BAAC

Indeed, order that has one and only one of A,B, and C in a column will give the same sum BAAC.
