According to the Q and A, two on one defense generally is not to be regarded as a blockade:
Game - The Game » ROBOT Actions » G25
Q577 Q. Does G25 have the potential to apply (at the referees' discretion) to all types of 2-on-1 defense, or is the intent limited to field-centric blocks? Could intentionally impeding 1 robot with 2 defenders qualify as blockading if no other match flow is stopped?

A. We cannot comment absolutely on hypothetical situations. Generally, impeding a single ROBOT without blocking all traffic across the FIELD is not considered a violation of [G25].
Your mileage may vary depending on the regional you are attending of course
