Google Analytics question

[jollyhumper]

I've moved my blogs from blog.tgpdomain.com --> tgpdomain.com/blog, to get traffic on the same place, if you understand.
(At my provider a blog.tgpdomain.com is a standalone site.)

I've googled this and read some articles, but I just don't feel I get a clear answer.
Do you guys have any knowledge on this:
Is it a problem to have two google analytics on the same domain?
Ie: one for main domain and one for domain.com/blog

Some articles suggests issues, but I'm not sure what issues they actually mean
