In the Join Tables Platform, what's the difference between Update main table with data from second table and
Merge same name columns?

Update main table with data from second table assumes that the user wants to Merge same name columns.
So, it's kind of a special case of Merge same name columns.
If Merge same name columns is selected, then any selected columns from the Main Table [will be] Updated with data form second table.
So, no Merge same name columns without Updat[ing] main table with data from second table.
