So to avoid the defense from putting out the BR who just tripped over 1B, R2 intentionally runs past R1 to gain a dead ball knowing that s/he should not be called out at the end of the play?

Sorry, you cannot convince me that the present rule and previous interpretation is broken and needs repair. The ONLY reason I can envision for such a change is the inability of an umpire to do their job properly. JMHO
