Loke switched from his own power to being conected with Lucy.

I've come up with a few possible explanations why they didn't switch to their own power yet or at all:


 * Maybe he can only come to this world under his own power by retaining a link with the Spirit World and thus he can't just switch from Lucy to his own power, while the other way was possible due to them being in the same world.
 * Maybe switching away from Lucy carries the chance of disrupting the opened gate and thus send them back to the Spirit World for a few seconds, in which Torafusa could do great harm to Lucy.
 * Maybe switching to their own power would require a second or two, in which they would be extremely vulnerable. Caprico wasn't really pressing the attack much to begin with and by the time Loke switched, they stopped fighting alltogether in favour of a little chat, so that wouldn't have been a problem on Tenrou.
 * We never really saw Loke in a serious fight while he was in Earthland under his own power and Virgo didn't fight at all that way, so it's possible that terminating the connection with Lucy would diminish their fighting abilities. Not something you want to do in the situation they are in.
 * Considering how they didn't summon themselves when Lucy was in trouble against Franmalth, maybe something in Cube/Pluto is interfering with them, making it impossible for them to stay without the connection to Lucy.
