Incorrect text outline in Illustrator

I'm trying to convert a letter "A" to a shape using the Type -> Create Outline function. However, the converted shape does not maintain the straight lines in the letter.

Here is the original letter (before outline)

and zoomed in to the bottom right corner.

After being outlined, it looks like this

If you look closely at the bottom right corner (red arrow). The base of the letter is not horizontal (see red line for reference).

Could anyone reproduce this / explain why this is going on? I'm using the Helvetica Neue (Bold) font.

Thanks!
