I believe there is a typo in the description of the encoding space for rs3 in [31:27] only for R4-type instructions.
rs3
[31:27]

I propose :
If an offloaded instruction uses the register file source rs3, then these are encoded in instruction bits [31:27] if the instruction uses the major opcodes MADD, MSUB, NMSUB, or NMADD (R4-type).
