It's not clear from the language specification, but in this case 
with templates, I am not surprised that the order of execution is 
not the same as in the source file. Probably it does fit with the 
order in the source file if you take into account where the 
template is instantiated in that file (but you shouldn't depend 
on that).
I strongly recommend not to depend on the order of multiple 
static this execution, by either rewriting things or by including 
some logic to make sure things are called in the right order 
(checking that something has already run, and running it if not, 
or cancel running it if it already ran)
