onmi --- the reason behind the observed results (including the crown rot) could be related to the growing conditions - which also includes how the orchid is/was grown.
Did a flower spike ever pop out from that crown area for the last flowering?
Anyway ---- let's assume that both orchids were repotted and then grown in 'exactly' the same way. And assuming that the slow growing (or non-growing) orchid had crown rot in the past.
One orchid might have happened to been more resilient ----- and so didn't suffer crown rot. Just like one person might be more resilient than another person in terms of developing health issues.
The history of the orchids (eg. how long were they growing there for before the repot) and growing conditions/method (watering technique, where is the water applied to the plant/media etc), air-movement details in the growing area, media type, watering schedule, fertiliser and mag-cal applications ------ pretty much everything ---- could help determine possible reasons for the situation with that one orchid.
If the orchids are generally and continually provided suitable growing conditions, they usually just keep growing nicely.
Whatever happened after the repot caused a setback in growth. Enough information/details will be needed to determine what needs to be done or could be done to improve the situation or avoid the situation.
