Quote directions

"Tips for Quote submissions" in the contribution form says:

"Please do not use separate lines for directions."

On the other hand, the Quotes help page says:

"You can include stage directions [...]

You can put them inline (i.e., with the character's speech) [...]

or on their own line"

and

"Standalone stage directions or notes like "first lines" count as a separate line."

So what is the meaning of the rule in the Tips?
