Why did my male coworker (who likes me) lie to me and tell me he's planning on resigning and gave me his resume to review?

He is about 14 years older than me, and much more senior than me, with much more experience than me in the professional field, so i can't understand why he would ask ME (someone much younger and with much less experience) to go over his resume, and he asked for my feedback?

I later found out that he's not planning on leaving any time soon, and that in face, he's staying here for two years.
