Why compare address?

[sctarget]

When I read context from a serialized string and use the context, my program crashed.
The reason is "Context mismatch" or "inconsistent contexts".
So I wonder why compare the address of context?

I think this is caused by

HElib/src/keys.cpp

Line 1333 in 3e337a6

// VJS-NOTE: why are we comapring contexts, rather

There's a comment that asks "Why are we comparing contexts rather than addresses", and the answer is "because of serialization, the context in the ciphertext may be different from the context in the secret key".
