Triple squeeze

I encountered the following hand this weekend:

Dealer:West
Vul:Both
Scoring:imps
T876
J
K82
Q9752
J543
A82
AT63
JT
92
T97654
95
843
AKQ
KQ3
QJ74
AK6

The auction was pretty standard, ending in 3NT played by South. LHO started with a small . 11 tricks were easy, but perhaps 12 were possible by means of a squeeze. So I took K and played a low to the K. LHO hesitated, so we know where A is. Next was the J, which is necessary to rectify the count for a squeeze. With normal layouts and if the J holds, we have 3s, 1, 3s and 5s = 11 tricks, perfect for a squeeze.

J held, so I played a to my Q and LHO took the Ace (mistake). He returned a . After cashing all my s, I ran the s. This is the position in the end:

Dealer:West

On 5 I discarded K, and LHO was squeezed in 3 suits. 3NT+3 won us a full imp, it's not much, but in MP it would've been a top.

I have no idea why LHO didn't take his Aces. From the auction he should've known his partner had nothing, and creating a third trick was impossible.

Note that if you don't play J, the squeeze doesn't work. When LHO holds up his Ace one more round the squeeze also doesn't work, because the communication to my hand is broken.
