I did the lab a month ago, and if I remember correctly, the reason R1 needs
to reflect the routes is because the link between R1 and R3 is an IBGP link,
for example. Any updates coming in from an IBGP link will not be forwarded
out other IBGP link(s). In R1's case, the other IBGP links are to R2 and
R5. If R1 doesn't reflect the routes to them, they will never get updates
originated from R4.
