After you move-in, what's villian's perception of being clocked?

[NYWalker]

Here's one hand in Sunday's WSOP NL $2000 shootout.
I was at table 13 seat 8. Level 1, 25/25. I had 1650. Villian had 2500. Villian's loose but lucky in the first few hands.
6-handed. Villian in CO raised 4BB (100), I was the SB and looked down KQs. I called 75. Others folded. Two players.

Flop K72 (rainbow), I bet 200. Villian called.

Turn Td, I checked and villian fired 450. I pushed all-in with 1300. Villian looked very sick after I pushed and I immediately narrow him down to JJ or QQ. He thought it for 2 minutes and said:"I didn't like the T..." 2.5 minutes... I decided to put pressure on him and called clock. When floor man was there, villian suddenly called and showed 99.

The river was a 9. He said to me"if you didn't put clock on me, I'd flod, really! Because I thought you were bluffing me when you called clock, I put you on AQ." (is this true?)

I'm not talking about being beaten by 1:23 odds here. I'm thinking is this the general reaction of being clocked?

So, when you move all-in with best hand and hoping villian to call, would it be helpful to put clock on him so that he would think you were bluffing?
