Yes. Temporary values end up being used in a binary operation sooner or
later, so any extra bits resulting from overflows get cleared. These
"final" results, on the other way, are only being added to 'H'; these
'H' values never go through binary operations. After too many cycles,
the accumulation of overflows ends up causing problems (e.g., loosing
bits).
