Length of redefined fields

Is it expected behavior for redefined fields to have same length as fields which they redefine?
Let's say we have
07 AAA
10 BBB PIC X(06).
10 CCC PIC X(13).
07 DDD REDEFINES AAA PIC X(16).

And then in parsed schema we'll see
7 AAA r ... ... ... 19
10 BBB ... ... ... 6
10 CCC ... ... ... 13
7 DDD R ... ... ... 19

I would expect length of DDD to be 16.
