Thanks!  We’ll explain in the next version.
“Tail loss” has become a common term in transport - because it’s a common problem: e.g. web transfers are usually short, and it’s not uncommon to lose just the last few packets of them (hence “tail”) - but then, for these packets, the sender never gets a DupACK, and all that helps is a timeout, creating significant delay.

Cheers,
Michael
