About the 234 known OBR errors

Let's try a similar play at first. Batter hits a slow roller between F1 and F3. F1 fields it but is off-balance and begins to stumble. While stumbling and falling F1 attempts to tag B/R who successfully avoids the tag but in doing so it messes up his running cadence such that he runs over 1B without touching it. F1 is able to crawl over and tag 1B barely before the B/R is able to check his momentum and come back to 1B. Is B/R safe because "the force" was off and he had to be tagged instead?
