Sugya – יושב ומצפה

Major Question:

If ר”ש does not hold of מיגו דאתקצאי   than why does he require the condition of יושב ומצפה?

There is a major machlokes between ר”י & ר”ש if a lantern that was lit at the beginning of Shabbos remains Muktzah for the entire Shabbos even after the flame is extinguished.
