Clues in the scene
The speaker points to a pot protruding onto a footpath.
Its current position protruding onto the pavement provides the reference point for “inside.”
Each choice explained
The pot toward the inside of the property — Best fit
Moving the indicated pot into the property preserves both the object and the direction specified by the request.
Only the plant out of the pot — Does not fit
Nothing asks for the plant to be removed from the pot. Doing that would also leave the pot in the obstructing position.
The footpath toward the road — Does not fit
The object to move is the pot, not the pavement. Relocating the walkway invents a much larger alteration.
All pots to a disposal site — Does not fit
A small position adjustment is requested. Disposing of every pot changes the number of objects and the kind of action.
Same words, another scene
During a photo shoot, a pot stands at the edge of an indoor set. The photographer uses the same request and marks the intended position, with no pavement involved.
“Inside” now refers to the set and composition. The pointing gesture and purpose of the task establish the direction.
Should I move the whole pot to the spot you marked?
Literal meaning
A request to put the pot further inside than its current position.
What these words cannot tell us
The property boundary, exact distance, ownership and applicable passage rules are not established.
A question to ask in real life
Would moving it to this marked spot leave enough room to pass?
