Do SD mode and SPI mode have different response formats for R1?

I figured out that R1 response format is different in the STM32 specification as the below

But in the Physical Layer Simplified Specification, there is a definition of R1 Format.

Actually I expect that R1's response format is supposed to be the same in everywhere.

But they appear different format in different specification.

Can I get some explanation for this to understand?
