As pps above have said. However sounds like the parent reacted to being unable to manage a developing school attendance situation and parent jumped into EHE to avoid court action, pressure etc, which is likely to rear it's head again unless the child's PDA profile has changed significantly.
Removing pressure may have changed the immediate situation, but I'd be concerned for both parent and child's future if parent's just hoping that it's all just going to somehow be better now EHE hasn't worked out.
If they find themselves in the same situation again, there may (also may not) be opposition to resolving it by EHE again, and parent may find themselves in very stressful situation choosing between child's needs and their legal situation.
Might be helpful to know: An EHE child's parent can request the LA to carry out statutory assessment or reassessment of SEN's and LA must consider it within same statutory timescales and in the same way as any school placed child. A good EHC could make a big difference to successful school reintegration.
(Also less likely but worth knowing: when a child believed to have SEN (with or without EHC) needs HE because they can't manage school attendance, (as opposed to Elective HE) but parents can't provide education, if the LA agrees child can't manage to be educated via school; LA can choose to organize SEN provision elsewhere, including in the child's home via tutors. It's allowed for under section 61 of the 2014 Children and Families Act, but there should be a clearly written up EHC detailing it.)
