join condition order

All we need is an easy explanation of the problem, so here it is.

Given a simple query like this

SELECT * 
FROM table_a a 
inner join table_b b on b.id_from_a = a.id

Does the order of the on clause matters? In the example above I always put the recently joined table on the left side of the equal sign and on the right side I put the first table

Would

SELECT * 
FROM table_a a 
inner join table_b b on a.id = b.id_from_a

perform the same way?
