Last week, we read the first two lines of the second mishna on 114a. Before we continue, you should review those two lines, with Rashi and the Rashbam...
We began the gemara, with the statement of Resh Lakish that "mitzvot tzerichot kavana," mitzvot require intention. The gemara then proceeds to reject the derivation, explaining the mishna in a manner consistent with the position that mitzvot do NOT require kavana.
Rav Simi requires that each participant in the seder have his own set of matza, maror, and charoset; Rav Huna declares that one set is enough. The immediate question is, why? What is the consideration behind their positions?
The gemara here addresses the meaning of the term "lechem oni," found in the Torah to describe matza. Shmuel first suggests that "oni" refers to a word from the root meaning "to recite." He explains that matza is "bread over which many things are recited."
Remember that the Mishna is an independent work, written several hundred years before the Gemara. Hence, this mishna is a direct continuation from the previous one, and not from the last gemara that we learned.
