I agree. We should have diff(a,b) == da / db. Commercial Macsyma also
has this bug.
The function depends should do nothing (or signal an error) if it the
dependency
already exists. I think you should file a bug report.

Subject: [Maxima] Does this behavior make sense?
c1 depends(a,[b,b,b]);
d1 [a(b, b, b)]
c2 diff(a,b)
3 * (da/db)
Shoudn't it be da/db?
