Q: find my iphone issue

The phone was not turned off and it was active on both 3G and home network

I could not understand why my iphone was showing a status of offline on the find my iphone app.. after locating the phone (I had simply misplaced it) and determining that the phone WAS active and both the 3g and my home networks were showing as active, I decided to shut off the phone and restart it to see if I could get it recognized on the find my iphone app and sure enough, as soon as I did that, the phone was located by find my iphone and showed its location. The phone was NOT off when i was trying to find it the first time. This is why I am asking if there is an anomoly.
