If the only alternate world Tamara knew was Neverland (due to her strongly implied connection with Pan), that's probably where she thought of the portal opening when she tried to send Emma through but it instead took Niel. Besides, she wasn't initially intending on taking Henry to Neverland... so it's a more plausible coincidence that Niel would end up in the same realm as Emma and Co.
