no, it is not.

block is obviously block data :-)

Thus, it is a Y, U, or V block of data.
For IFrames, this is image input. For predicted frames
this is residual input (after motion compensation)

I don't have the code handy, but block is defined by a
DECLARE_ALIGNED_MATRIX macro "call" either in the function
or the caller (and passed down the callee).
