I was taught the exact same thing and for the same reasons.
The lore I was told at the time was that you

didn't matter if they were all on the same line with semicolons or not

What I was taught was:
% sync
% sync
% sync
and never:
% sync; sync; sync
The theory was that by waiting for the shell prompt each time, it gave the
buffer pool enough time to be flushed.
