2nd Week, First Excercise - in/out of THEN

I compared my result to the answer and found that the completion of the Word file was done outside of the THEN part of the IF in the answer, while I put it inside of the THEN. When it’s outside, doesn’t the s/w still need to look at it once deciding to skip the current row, thus adding processing time (insignificant for a few rows, but potentially substantial in a large spreadsheet)?
