Peter,

I don't recall the exact reasons as I've managed some sleep since then. Looking at it, I can see a couple possible reasons though.

Table 3-4 timings are from Controller EOP to Responder SOP. Since there are no BREAKS this can make things confusing sometimes to detect SOP for the Responder.

You could have multiple responders on a link that respond far enough apart to get multiple discovery responses with no collisions in that time frame.

Because of the possibility for error, I think the safe position for 'dumb' splitters was to remain in this reverse data flow direction for the entire response window to ensure things functioned.

Regardless of the reasons, it doesn't really matter as this is a SHALL requirement so all in-line devices are required to observe the timing requirement.
