Here is a short introduction.
On the Sabbath Day, Jews are not allowed to work. If a Jew works on the Sabbath, he must bring a sin offering. But let us say he knew today is the Sabbath but he forgot about two different kinds of work. Does he bring one sin offering or two? This is no mystery. WE know already that he brings two.
[These sin offerings are stated in the Holy Bible in Leviticus chapter 4.]
Now there are lots of kinds of sins for which a Jew has to bring a sin offering. Another example is eating blood or forbidden fat. So lets say he forgot about the prohibition to eat blood and also forbidden fat. The we also know he brings two sacrifices. [This can get to be expensive. Each sacrifice has to be a sheep or goat. You can't bring turtledoves or pigeons except for specific sins.]
We know what kind of work a Jews can't do on Sabbath because the Bible tells Jews not to build the Tabernacle on the Sabbath. So we know what ever type of work was needed for building the Tabernacle, we can't do on the Sabbath.
Rabbi Zachai said Shabat is more strict than other commandments in the Torah because if one does two acts of work by one "forgetting" on Shabat he brings two sin offerings (Leviticus 4), while for other commandments he brings only one

What it seems the Gemara is trying to ask is that Shabat has divisions in side of it while other rmitzvot do not. But if that is what it is trying to ask then why does it not ask it? Instead it goes into the problem in an elliptical way. It asks: What two works are we talking about here? If harvesting and grinding then but other mitzvot we are talking about forbidden fat and blood. But there two there are two sacrifices.
If on Shabat we are talking about two acts of the same kind of work like harvesting the also by blood there would be only one sacrifice.
