How to clarify ambiguity of the left arrow in google search autosuggestions?

Until recently I found the arrow next to each of the suggested keywords are tappable and will prepopulate the string to the search box for users to further refine the keyword before performing the search. Initially, I thought it is only a visual cue means "go to the search result of this suggested keyword", although the arrow pointing left somehow confuses me because usually, the arrow would point right if so.

This pattern is found in Google search and google map search on mobile. Wanna know how the community thinks about this.

• Is it a conventional UI pattern?
• Does the iconography communicate the purpose well?
• What alternatives do you have to improve the clarity of this feature?
