May be its simpler to rephrase it and following somewhat this way:
Which means " PMD support different scatter-gather styled input and output buffers i.e. both can consists of multiple segments"
>+ - "OOP SGL In LB Out" feature flag stands for

Which means "PMD support input from scatter-gathered styled buffers , but can output to linear buffers.
And better to replace "flat" by "linear" to be consistent with name.
