Did Button play this correctly???

[Webster]

2nd hand of the night - zero reads but my question is about the Button. What do you think about his play here!

As you can see I was left with a silly grin on my face and 60 chips. I fought my way back to end 4th and when I pushed all 1600 chips in with AK, the SAME button called with his A5 and I lost AK for the 14th time in a row when pushing.

He hit his 5 and I LOATH AK!!
