You probably will be OK especially since you have the minimum inserted plus a little extra but in the end I would probably look at a longer seatpost to give you more confidence. I wouldn't want to have that looming over my head personally.

It is a fine post and Specialized generally does pretty well with their stuff though some goofy internal stuff sometimes that has me flustered (but I figured the solution so just need to find some micro shims and I think it should be smooth sailing). However having that much sticking out I would want more sticking in just to be safe and sure.
