Yes, it does.
It stores the MD5 of the original data at the time it stores the data
(in whatever form, be it as a delta or not. THe storage system is not a
simple RCS-like always-single-delta-in-one-direction-per-revision
svnadmin verify reconstructs the data for each revision from the
repository using the same functions that checkout would use, and then
verifies the data it has reconstructed against the original MD5's.

The people involved in subversion development (including me) wouldn't
design a system that had no data integrity.
