RDBMS Index vs. MongoDB Index

Under ‘RDBMS Index vs. MongoDB Index’ at https://university.mongodb.com/mercury/M100/2021_May_25/chapter/Chapter_1_Concepts_of_RDBMS_and_MongoDB/lesson/5e7e635acbcbee7c642d54a0/lecture it says

Building an index on a set of fields in a collection is the equivalent of having an index that would be built on a set of tables.

Shouldn’t it say ‘…on a set of columns’ instead?
