IE Workbook lab 3 Task 2.1 and 4.1

Hello experts,
I am reviewing this lab, and I saw, that on Task 2.1 it says that is necessay
for Lo0 on R4 and R5, to be announced with a mask of 32 bits, so the LDP
peering on task 4.1 needs both loopbacks to be a /32 mask.
I do not understand exactly why, so could anyone please help me with that ?

Thanks in advance and best regards !!!!
