Both tests require the test image to have a specific size; this cannot be guaranteed by vpc (unless tuning the test specifically for that format). It is safe to exclude vpc from 004 because what is tested there is implemented in a generic part in the block layer and not format-specific. It is safe to exclude vpc from 104 because for vpc basically every image size is "unaligned", so if that would break at some point in time, we would quickly notice just by running the generic tests.
