Question about Blips and reinforcement

[Hive Lord]

Greetings!
A question for all of you.
Rule book says that if a Terminator is at least 6 squares near a Genesteeler's access point, Blips placed there cannot enter the ground, and must wait until next turn.
Does it means that a Terminator standing still near an access point actually can "block it" potentially forever? Or have the blips to wait ONLY one turn before entering freely from that access point?
Sorry for my poor english, and thank you all!

In the English rules it specifically says that a blip can only be forced to lurk for one turn - it can come in on the next turn regardless of the Marine's proximity.
Also in the 1st Ed rules they made note that if a Marine was right up at the entry point a blip could convert and the Genestealers attack from off the board.
