Last time I remember Hashirama's gate was holding the ten-tails just fine he only had touble with Bjuu Obito. It's a MASSIVE leap of faith that because the sword can absorb relatively weak people it can suddenly seal a being of simply incomparable power.

What we've seen the sword do is absorb two stationary targets of relative (compared to biju) low power when they were pierced. What we've seen is that higher-power beings were noticeably resistant to restraining attempts by seals.
