Argument Comparison Order

Question

I am an experienced programmer and therefore I feel a little confused asking this question, but decided to do it anyway.

I am reading this book and also see various examples on the net where the order of the arguments in the comparison operation is canceled, and I wonder if there is a reason for this, or simply because it looks “cool” and does the same.

Example:

I would encode:

if(bool_variable == YES)

while I saw in this book and in various examples

if(YES == bool_variable)

Explanation?

Thank you, ton!
