theoretically. but three things:

1. hondas don't leak much into the oil from gasket failure - the oil and
water passages are well distanced. cracked block is more likely to
cause this kind of leakage in a honda, and that's very rare.
2. if /that/ much coolant was in the oil, over a quart [20%-30% water
content!!!], there would be mayonnaise everywhere, including the
dipstick, not to mention under the filler cap. advice to check the
coolant level [when cold] might be handy in this situation.
3. clogged oil filters and general sludge buildup can affect drainback
times.

i vote for the simple stuff first like the op making sure the oil is
dipped on level ground. sounds trivial, but i'm not joking - had a
similar issue with a buddy of mine just recently. ended up having to
drain two quarts from his overfilled toyota.
