Contexts don't separate backend engines, they only capture the
internal GPGME state of a crypto operation. If one crypto operation
modifies the backend engine state, that can be observed by another
context using the same backend engine state. Remember that GPGME is
only a layer around the backend, it does not capture any state of the
If you actually want separate backend states, you need to create a new
home directory for gnupg, and populate it with the state you want it
to have somehow (manually). Then you can use the "set engine info"
operation to configure the context to actually make use of that second
