OP didn't specify there was a time lapse between the two spells....they could have been an overlap in casting for all we knew. Without knowing the specifics it was hard to say for certain based on the OP. Could very well be an issue with delayed update on position if you were moving towards the caster while he/she casting. Think Escape has a more narrow radius than Curaga V. Not sure on that....but it seems pretty easy to get out of range of an escape or tele.
