Isn't that just another way of saying Minimum OAL??
Don't seat your bullets lower than the Min OAL or you will kabom!
Anything over, up to Saami Max is OK.
Look at Hodgdons data for say the 230 gr bullet in 45 ACP every dang one of them is 1.200 for every powder.
I asked them about this and was told for testing, keeping them all the same to determine a safe length no matter what bullet so everything is consistent and we do not blow ourselves up (not in those exact words)
Same reason they use Mag primers for any mag load even though the powder does not require it.
