Everything I've ever read about it said it was no problem and not an indicator of readiness to be trained again. On most routines where I trained every bp twice or thrice a week this was a necessity, at least in the beginning stages. My strength never suffered but my overall feeling during and after a workout and my pumps took a hit for the worse. Then you have to also factor in that the less often you train a bp, the more sore it gets and the longer it stays sore as well.
In short: the consensus is always that it's just fine, personally I'm still in the middle about this, I honestly don't know how much and if any truth there is to both sides
