A Midrash deduced from the use of the word "this" in that the work of the Menorah was one of four things that God had to show Moses with God's finger because Moses was puzzled by them. Similarly, Rabbi Hiyya bar Abba said in the name of Rabbi Joḥanan that the angel Gabriel girded himself with a worker's apron and showed Moses the work of the Menorah, for says, "And "this" was the work of the Menorah." (The word "this" implying that something was held up to illustrate the instructions given.)
