bluehair,
Actually, no.
The running lane proscriptions only apply to plays being attempted at 1B.
I applaud the fact that you are actually reading the rules. As you have discovered, there are a number of ambiguities (not to mention occasional contradictions) in the text of the rules.
If this stuff interests you, I would encourage you to obtain a copy of the BRD, which is probably the best source of authoritative interpretations to clarify these ambiguities and contradictions for FED rules.

I might add that I, personally, am waiting for the 2007 edition before ordering another copy. (I'm fairly certain that I am not the only one.) But I already have one.
