I sent this email to my Bishop.. Is there something I am missing?

Bishop,

A couple of months ago I asked about the Deacons helping with setting up the sacrament as we only have one teacher. As I reading in D&C 20 this afternoon I came upon these verses. Please note verse 57. Doesn't our situation meet the "If occasion requires" clause? Am I way off here in my interpretation of the D&C?

53 The teacher’s duty is to watch over the church always, and be with and strengthen them;
54 And see that there is no iniquity in the church, neither hardness with each other, neither lying, backbiting, nor evil speaking;
55 And see that the church meet together often, and also see that all the members do their duty.
56 And he is to take the lead of meetings in the absence of the elder or priest—
57 And is to be assisted always, in all his duties in the church, by the deacons, if occasion requires.
